Thug Doing Thug Shit Gets Arrested By Cops Doing Cop Shit

If I could teach the criminal side of Black America one single thing, it would be, “There is such a thing as a holster. Try using them.” It’s about safety.

Copper Remover Thrash: Modern Spartan Systems vs. Sweet’s 7.62 vs. Wipe-Out

The motivation here was to test Modern Spartan Systems line of gun cleaning kit against established known quantities with proven performance. Their promise of no foul smell, lack of toxicity and some of the other claims they made caused me to get curious enough to do a Pepsi challenge for their whole cleaning system. This includes Accuracy Oil; which claims to increase velocity & cut group size & extend barrel life. It also includes their Carbon Destroyer and Copper/Lead Destroyer and their Carbon Destroyer.

I’ve already started long term testing of their Accuracy Oil’s claims at longer barrel life and improvements in velocity, group size and consistency. Those experiments are continuing and I’ve built an impressive data set so far with more coming in every week. In the meantime, the fundamental ability of the fouling removal products to perform like they say it will had not yet been established by any kind of usefully conducted experiment I could find. So, I’m doing it. I’ve already put the Carbon Destroyer up to the Pepsi challenge and it flat works. It’s pleasant enough to use and worked like a charm on everything from revolvers to pistols to high power modern rifles to black powder cartridge rifles. The way it worked on our set of Trapdoor Springfields was terrific. What about the big one though…COPPER!?! Let’s git’er done.

I’ve got enough barrels around with sufficient fouling, including some I’m entirely willing to destroy, to give a good test of effectiveness and side-effects. In the spirit of experimentation I set up the first round of testing with 3 barrels:

  • Stock Glock 21 barrel. 1000’s of rounds since being cleaned.
  • Savage 10 .308 24″ heavy barrel, >500 rounds since cleaning.
  • Black Hole Weapons 26″ .223 barrel > 200 rounds since cleaning.

Cliff’s Notes: In short, MSS’s Copper/Lead Destroyer is very effective. Zero question about that.

More detailed findings and experimental procedure:
C/L-D not as strong as Sweet’s by a mile nor is it as strong as Wipe-Out as a copper remover but it’s a lot more pleasant to use than Sweet’s and less messy than Wipe-Out. This is about removing copper and copper fouling is hard to remove well without damaging the barrel steel. You either get mechanical action which is by definition damaging to the bore or you get chemical action which may be damaging to the bore. Bore damage can be dependent on the length of time of exposure to chemical agents and some of them are really nasty for everyone involved.

To start I took a G21 barrel that had been belled just in front of the chamber by a squib. It had previously had Carbon Destroyer run through it and then was soaked overnight (26 hours) in Copper/Lead Destroyer, hosed out and stored. I ran some Wipe-Out into it and gave it 15 minutes to soak and pushed a patch through. Zero color change on the patch. Then I ran some Sweet’s in it and let that soak for 5 minutes and pushed a patch through. Zero color change on the patch.

Ok, that’s the null result I was expecting. The barrel was clearly clean of copper to begin with but you don’t know the state of fouling before the 26 hour soak. Could have been a lot, could have been a little, could have been none for all you know, right?

Now to find the more interesting results. I took a factory Savage .308 Win barrel that I’d abused and not cleaned in literally years. It had at least a couple hundred rounds put through it before it got yanked and set aside. I started by running patch of Sweet’s through the barrel without running a brush through it, hoping that the carbon that stayed behind would protect some of the copper from the Sweet’s to serve as an indicator later. It came out with gooey gobs of blue on the patch with no soak at all, just applied and patched out. I immediately took the barrel outside and hosed it out for a solid couple minutes to keep the Sweet’s from finishing the job. I plugged the breech with a .45acp case and filled the bore with Copper/Lead Destroyer and gave it 2 hours to soak. After the soak I ran a patch through it a couple times (remember, no color change on the patches, C/L-D doesn’t do that) and then went and hosed it out. Now I needed to see if there was any copper still in there so I took the Wipe-Out and ran that in the barrel and gave it a 20 minute soak. After pushing a patch through what I found were traces of blue streaking on the patch and plenty of black and brown. Not much blue but enough to tell me that the carbon was in fact protecting the copper. There wasn’t enough copper coming out to make a good finish up to the experiment on that barrel so I reset the experiment by virtue of moving on to the .223 barrel.

The .223 barrel started with at least 200 rounds since the last even partial cleaning so it got a thorough carbon removal with Carbon Destroyer. When patches wrapped around a bore brush came out without any black or brown on them, I called that done. I put a fired case in the breech, closed the bolt and then filled the bore with Copper/Lead Destroyer and let it soak for 2 hours. Then I pushed a pair of patches through which came out not much different than they went in. Now to see if the C/L-D worked I ran a patch of sweet’s down the bore, gave it a solid 3 minutes to soak and pushed another patch though looking for color change and got NONE AT ALL. That was a null result I did not honestly expect. I expected to find some copper remaining, I mean Sweet’s is as aggressive as it gets. But no.

What’s that all mean? Leave the Copper/Lead Destroyer to soak a while and it works as thoroughly as Sweet’s or Wipe-Out. I really like using C/L-D way more than Sweet’s. I can’t even stand opening the bottle on that cat piss smelling Sweet’s. I actually really like Wipe-Out too and will continue to use it at the range because it’s super easy to deal with there. At home though, I think I’ve found my new cleaning product suite. All the chemicals I need are now finally not unpleasant.

Modern Spartan Systems – Copper/Lead Destroyer: No bad smell. A detergent-y smell similar to cold bluing solution is what it reminds me of most. The directions say you can leave in barrel safely for many hours, even overnight. I left it in a G21 barrel for 26 hours with no adverse affect noted. MUST use a carbon solvent prior to applying for it to be properly effective. Modern Spartan’s carbon remover works great. Getting C/L-D to stay wet in the barrel was another story. It dried quickly in my low humidity area. I eventually stuffed a fired case in the breech, stood the barrel up and filled the bore on rifles. On pistols it was easier to soak a narrow strip of paper towel in it and thread that down the bore and let it sit that way overnight. Directions say 3-5 minutes of soak. I got best results on heavy fouling after 2 hours. No color change on the patch so it’s a little hard to “know” when you’re done.

Wipe-Out: It’s got a smell but nothing like Sweet’s. Can leave in barrel overnight, no ammonia. It’s a foam that expands so some will end up in your action and it’ll probably drip out of the muzzle so, a little messy to use. Patch’s change color to blue if copper is present. Works on carbon and copper. Usually 15 minutes is more than sufficient as a soak time.

Sweet’s 7.62: Super strong ammonia smell. Do not leave in barrel longer than necessary, clean residue off skin and gun thoroughly immediately after use. Known to be hard on steel. Must use carbon remover prior for full effectiveness.

I have video and all that jazz but it’s not very interesting TV. It’s just me slowly, methodically and painfully boringly working out the surprisingly obvious. On the upside, MSS’s stuff works like a dream so far. I can officially endorse the Copper and Lead Destroyer and the Carbon Destroyer because I have proven beyond any doubt that they work as advertised.

Now about that Accuracy Oil….

ExactShooting.com Custom Sizing Die – Experiment #1 Results

So we have initial results. I’d like to thank you all for the views on my video.

We will be testing this die set more over the next year. This is out of my pocket and out of my own curiosity. I have the credit card bills and had the arguments with my wife to show for it. I must caution, because of some things people seem to have in their heads, that this isn’t ever going to make a 1″ gun into a .5″ gun. Anyone suggesting such a thing is either a fool or a liar. What you should be expecting is to reduce variability in your ammo which reduces things like flyers & SD’s. Effects on group size, maybe small ones should be expected as a normal effect of better consistency but because barrel harmonics are involved there so heavily it’s best to keep your hopes in check and out of the land of silliness.

I set up a partially blinded experiment with unfired, 2x fired and >5x fired cases. We (Coach and I) sized up 50rds of each from my Exact die and 50 of each from Coach’s Redding die and tested that in Coach’s rifle. Coach’s rifle has somewhere over 1900rds down the pipe now which is a concern as you’ll see soon. We set the ammo up identically in everything from components to neck tension. We ran 10 shot groups which were composed of 2 non-consecutive 5-shot groups fired at the same aim point. Coach loaded, packed and labelled the ammo boxes (labels are “1” and “2”) and didn’t tell me till after the shooting was done which was which. I pulled the rounds from the boxes, logged data and called the target to engage while coach did the shooting. That way neither of us knew during shooting which ammo was being fired at any given time. That was the best way I could think of for me to pull out experimenter induced bias with a research team of 2.

The result of the first accuracy test was null. That is to say that the numbers difference in average group size was not outside the level of statistical noise. The exception was with brand new brass. It always shot more consistently than reloaded brass and so I removed those results from the full data set due to the noise they introduced. We also weren’t meant to be testing new brass as that would not apply anyway but I wanted that data for another experiment I’ve been running. This is all precisely what was expected. I expected no big result (but certainly hoped for one) in accuracy simply by going to full length resizing and having extremely consistent neck tension and headspace.

Because the result is null though, we’ll re-run the experiment on that rifle just before we replace the barrel, just to verify the results reproduce reliably. We also did some velocity testing as part of that and there was no statistical change in average velocities or SD’s except that in the new brass loads but it was more consistent set to set. Why pull the barrel? The rifle used for that run of the experiment now has ~1900 rounds through it in 6XC with a single load spec (38.5gr H4350, F210M, Norma brass, 115gr HBN coated DTAC). The load is mild; generating only 2800fps, but we know that that barrel is within a few hundred of being pulled on principle; if not actual need, as far as match work goes and it may not be capable of the repeatable accuracy that might show up with the Exact die. So, we’ll try another barrel. A new one. Actually, a new two! So stay tuned, there’s more to come.

In September I purchased 2x new barrels which I got as blanks from the same production run (from Black Hole Weapons). I purchased a new custom reamer in 6XC that produces a chamber that is very tight to the dimensions of the Exact die. Thankfully you can order a reamer with any number of customizations and it’s still the same price as a custom reamer with just 1 custom dimension. Unfortunately it takes weeks for such a reamer to be made. Over the winter I handed the whole works over to a gunsmith friend of mine that also makes ultra-precise gauges as a business. So, he has the equipment and skills to set up barrels that are truly as identical as we could make them and identical enough for a useful experiment to come out of it despite a sample size that’s extremely small.

Anyway, I got both barrels cut, profiled and chambered identically. It was at great cost too. The cost to set each one up was double what I normally pay him to set up a barrel for me for each barrel with over 15 hours of work on each one. These are our new match barrels for the next 2 seasons too. Coach and I will be shooting from the same ammo box so we can share data. Maybe we’ll pick up a few points on same-day wind calls.

We did have a non-null result and from a different direction, which I also predicted. That was that with loads that were sized with my ExactShooting.com die we never had trouble closing the bolt. It was, in fact, always exactly the same effort. On the cases that we sized on the Redding neck die that Coach uses bolt close effort was either not much or a TON. Some post-facto testing later on with coach’s FL die showed the same random bolt close effort. This is obviously due to random headspacing which means that Coach’s FL die probably needs a thou or two buzzed off the bottom. Irrelevant though because we’re testing what’s available out of the box and his FL die out of the box didn’t cut it so I suspect that a lot of FL dies out there may be a little long or short and aren’t sizing things like people think they are.

That is only the results from a well used barrel. We will be running this exact same test using the 2 newly set up barrels. One will be on the same gun (Coach’s match rifle) while its twin which now has just under 400 rounds on it is on a different my “Hot Dog Gun” match rifle. I don’t expect any difference but I could wind up being surprised. The new barrel on Hot Dog Gun is extremely accurate so far, better than Coach’s rifle on its first day. We’ve already developed a load for the new barrel that runs things a bit faster (2980fps) so hopefully with more pressure more differences might start to manifest.

One of the cool things about the ES die is you can pull the body/shoulder portion out and still use the neck sizing portion which itself is easily adjustable for neck tension and neck sizing depth. When you start getting hard bolt close you can dial in .0005″ or .001″ or .0015″ or whatever amount of push-back on the shoulder with an easy click adjustment and know it’ll give that to you exactly. We’ll be running a neck tension accuracy test here real soon. We’ll see if .0005″ increments makes real differences on paper. First though, I’m ordering some brand new brass for that test.

Cost is fairly high for these dies but not unprecedented. That’s true but, beside the point. If you have the money then that’s not an issue anyway. Functionality is THE issue. It’s perfectly functional and makes it super easy to dial in neck tension at .0005″ increments for those really finicky loads, to dial neck sizing depth at .020″ increments and to dial how far back you actually push your shoulders in .0005″ increments. They’ll make one to a reamer print too. How precise are the dies? Well I had my machinist do some gauging to see if they were that precise and he was pretty darned impressed.

For benchrest guys and F-class guys, I think this is really packing the potential to up their game a bit but only because those guys tend toward having done everything else already. BR and F-class are the only places I can think of of offhand where neck tension and headspacing are tightly controlled by the shooters both routinely and with an obsession rarely seen.

Is it going to help joe sixpack? Well no, to be honest. Joe doesn’t know enough to get the potential benefit to begin with. Owners of this die will 100% want to keep their brass sorted by number of firings. They’ll know about what spring back is and why it’s important to them and a lot more. They will be the type that can’t deal with unexpected 5’s instead of 0’s or 1’s in the 4th decimal place of a measurement. The right owner for this die is someone very much like me in the respect that they are prone to setting up narrowly defined experiments and to analyze the statistical data that results before forming opinions. They’re nerds.

For Coach and I the benefit is being able to share ammo and ballistics data in a match, not running out of time anymore on match stages due to bolt cycling problems, not overworking or insufficiently sizing the brass and being able to make subtle adjustments with truly minimal effort as precisely as adjusting a tactical rifle scope.

Upgrade Time: BallisticXLR Version 10.3 Is LIVE!

Version 10.3 is officially live. This much anticipated upgrade includes a new Loophole Shooting feature, an improved Calc Form, tons of minor formatting fixes and other improvements to make your long range shooting experience as rewarding and successful as possible.

NEW! Loophole Shooting Feature: In response to high demand the new Loophole Shooting feature has been implemented. This includes the required minimum vertical size of the loophole required to place a shot on target with the loophole placed 10 feet (3 meters) from the shooter. There is no other external ballistics application in the world that integrates this feature with your primary DOPE. At this time the Loophole data is only on the 100yrd/m increment Full Sheet tab. This is with the assumption that if you’re shooting from behind a loophole that you’ve got more time to set up your shots including setting up a sniper range card, justifying the extra data that’s on the 100m full-sheet tab compared to the 100yrd/m half-sheet tab. If there is sufficient demand we’ll add it to the 100yrd/m half-sheet tab in the next patch release.

Loophole Technical Details: The Loophole Shooting feature provides you a loophole size in inches or centimeters required to make the shot without hitting the edges of your loophole or the barrier it’s been created in. This feature requires careful measurement of your scope height. The level of precision required is now in the .0x inches zone but only if you plan to use the Loophole Shooting feature. If you do not ever need to use this feature then .1″ of slop in your measurement of scope height will be inconsequential.

Why Loophole Shooting: When BallisticXLR was partnered with the RexReviews project with TiborasaurusRex, Rex explicitly forbade providing this feature to the masses. Now that we’ve gone independent, we don’t have to withhold it anymore and in keeping with our custom of providing you the most capable system regardless of who might get upset about it, it’s now been released to the public. We are committed to providing continuous upgrades with new major features and minor features that are already planned as well as responding to the requests of those that use BallisticXLR.

Other Improvements: Major and minor improvements have been lavished upon BallisticXLR version 10.3 which, as our flagship product, it richly deserved. Some improvements include a simplified and improved Calc-Form, font size and color changes to make for easier reading in low light situations. We’ve put new Sniper Data & Shot record cards in to replace the older FM-23-10 derived versions. Quick start instructions on the inputs page have been clarified and simplified. Borders, colors, shading, contrast and may other elements of style have been tweaked to provide an improved user experience.

As always, the simple download is only $10. You should really consider getting a support entitlement as ballistics is a complex science and setting up a ballistics package as full featured as BallisticXLR can be a little daunting for the uninitiated despite our best efforts to make it as simple as possible. A basic Bronze support entitlement is only $50 and comes with a copy of BallisticXLR. We also have Silver and Gold support levels which increase the number of allowed support requests and reduce the maximum response time. All support entitlements also come with free upgrades for one full year! Don’t miss out on new stuff or 1:1 personalized help when you need it!

Existing Download-Only Customers: If you have purchased a download-only copy of BallisticXLR (does not include BallisticPRS or BallisticDLR) within the last 30 calendar days and would like the upgrade to Version 10.3, email ballisticxlr@gmail.com with your paypal transaction number & date of purchase and we’ll upgrade you free of charge.

Existing Support Entitlement Holders: If you purchased a support contract & download within the last 365 days you are entitled to a free upgrade to Version 10.3. To redeem your upgrade, email ballisticxlr@gmail.com with your paypal transaction number & date of purchase and we’ll upgrade you to Version 10.3 free of charge. This upgrade does not extend your support contract.

US Optics B-17 Review – Very Nice!

Epic scope. My only gripes (except the price point) are very minor quibbles in reality. Same perfect tracking, same great glass (actually some of the best ever in a USO), some real improvements in the turret setups. Some things are not so much improvements as changes but you can’t turn your nose up at a USO.

Barrel Life, Accuracy and Velocity – Columbia River Arms Wins!

I’m running a .243AI set up by Columbia River Arms (formerly Black Hole Weaponry) about a year ago. It’s a pre-chambered drop-in with a pretty tightly necked chamber set up by CRA. I’ve got it set at zero head space so between that and the Ackley Improved case there’s zero brass growth after 4-5 firings.
It’s got just a touch over 1000 rounds down the pipe and appears to be going strong. So far I’ve only had to push the bullet out .010 and add .1gn powder to keep everything tight to my original load spec. I don’t know what kind of life the pipe has left in it. I’m running 115gn 6mm DTAC bullets at 3200fps with a modest charge of very slow burning powder (RL-23). Pressures are pretty mellow but it’s, for sure, burning that powder all the way down the barrel. This is evidenced by the fact that there’s just the tiniest bit of flash in the first chamber of my brake that’s visible in low light conditions.
Corey testing out the CRA barreled Hot-Dog Gun at 900yrds.
In a more conventional barrel I’d guess I’ve have between 100 and 300 rounds more life before it’s just not match grade anymore (based on a 1200-1500rnd life expectancy) but I would also expect substantially more throat erosion than I’ve gotten to this point if that were the case. I started with uncoated 108ELD’s and quickly went to HBN (hexagonal boron nitride) coated 115DTAC’s. The rebated boat tail and pointed tip on the DTAC’s pulls the BC up to .620 which puts me up to 1mile of supersonic range. So far it’s been as far as 1500yrds and proven itself very capable.
Out of the gate I was getting 10 shot groups like those below (these are fireforming and load development groups, the first loads out of the barrel). After a little refinement they settled down to repeatable .5-.7MOA across 10 shots with single digit SD’s (5fps across over 100 rounds loaded in 3 sessions). The thing has since then been ridiculously consistent. Once I found an optic I could deal with in matches (I hated the turrets on Vortex Razor 2’s, U.S. Optics ER-25 was just too damned big, SWFA 16×42 was too much minimum magnification, etc… nitpicky stuff) in the form of the U.S. Optics SN3 3.8-22x58mm with a custom made PRS oriented reticle and 35mm main tube, I really started to have some fun with it including punishing the rifle with 10 shots strings in 90 seconds on hot days (hey, that’s the stage on the match). I wasn’t going to take it easy on this barrel.
I crossed the 1000 round mark last month at a match and I’d thought the barrel might be toasted then due to some repeated and huge misses on otherwise simple shots. Turns out it was just me. I clearly did something wrong to make those misses. I know that because I went out again this month to teach a long range precision rifle class and demonstrated most drills and techniques with my .243AI. It started out by making a .5″ 5 shot group @ 100 yards. At the end of the class it got to be time to see what I could do under some performance pressure so I got right down into the prone with my Columbia River Arms barreled Savage 10FPSR, dialed the parallax on my U.S. Optics SN3 3.8-22×58, extended the Accuracy Solutions BipodEXT, set the Accu-Tac SR-5 bipod to 45deg forward and slapped a 6″ 900 yard 5 shot group on the steel rapid fire in direction shifting 5-15mph winds while the student body looked on.
I’m using 45.6gn of powder now. It started at 45.5gn of Reloader 23 in a very tight chamber with Hornady brass. By the book one should expect to see 3000-3100fps with 44-45gn of powder in a 24-inch barrel with 100gn to 105gn bullets. I’m getting 3200fps with 115’s and only 45.6gn in a 26″ barrel. I’d expect to see 25fps or thereabouts per inch of barrel after 24″ but certainly not 50fps per inch from barrel length alone and not with a heavier longer bullet. I’m also not even remotely pushing this round. I can go another 3gn of powder before even starting to flatten primers but 3300fps only serves to damage steel targets and is technically against the rules. 3200fps is max so that’s what I’m running. I already damage quite a few targets at 3200fps anyway so I don’t need any help in that department.

Typically as I wear out a barrel I’ll see it shoot fine, fine, fine, start to open up, plateau, fine at plateau, open up more, open up more, open up more and it’s all downhill from there. After the plateau if it doesn’t quickly plateau again it’s getting there and it’s time to start planning my next pipe. I’ve already started planning my next pipe, a 6XC to match an identical one we’ll put on Coach’s gun. Nonetheless, this barrel is still good. Question is, for how long?

I know from prior experience that I get a little longer barrel life from the polygonal rifling that CRA uses. I’ve not burned out enough to get a useful statistical value for how much longer but I can speculate. Right now, given the throat wear and grouping we’re getting on Coach’s existing 6XC; which is at 1500 rounds so far, and the expected life of that Shilen barrel being around 2200-2300 rounds, I’m estimating; and trying to be extremely conservative in that estimation, that I’ll make it to 1800 rounds or further before this pipe is really done for match work.

The difference between .243Win (right) and .243AI (left) is shoulder angle, body taper, performance, case life and barrel life. The loaded round has a 108gn ELD-M in it and 39.5gn of RL-23 for fireforming.

That’s almost 40% longer barrel life than I initially anticipated, if it gets there. We knew that the HBN coating on the bullets would help barrel life so I’m confident it’ll get to 1500. We knew the CRA polygonal rifling means no sharp edges for the burning powder plasma to ablate would help too. We knew the Ackley shoulder angle would keep the flame vertex inside the case neck and that that would help too.

It’s just with all those things helping, we have no idea where this train is going to stop. If I go on throat erosion alone, calculating how far until the boat tail is up inside the case neck, then I’m looking at almost 3000 rounds of barrel life. That’d be 230% of anticipated barrel life and I just don’t see that as being realistic given the amount of powder being burned and the rapidity with which I shoot in matches. I’ll get that barrel pretty hot sometimes.

Shooting stage 6 at my monthly match with Hot Dog Gun in its current form. Targets are on the opposite hillside from 300-700yrds away.

I get higher velocities than one might expect from less powder than one might expect. I get longer barrel life than one would expect. I get amazingly accurate and consistent performance than one might expect (especially for a drop-in pre-fit). The thing turned out sub-MOA groups with fire forming loads. It did not like 55gn varmint bullets at all though. No surprise on an 8 twist. The chamber on it is very tight. It’s meant for someone who’s willing to turn necks if necessary (my inside neck diameter on a fired case is .2435). Thankfully I don’t have to neck turn. Lucky me, everything just fits perfectly. When I ordered it I specified that I would not be put off by a possible requirement to neck turn brass if that were what their reamer would require.

Much of this situation was and is by design. When I initially decided I wanted a fast 6mm I found what my options were and then picked a chamber that would maximize performance, brass life and throat life. I picked a powder that would give maximum velocities without pressures being tall or a lot of flash. I picked projectiles that had very high BC’s and would be routinely available in boxes of 500 (including a primary and backup bullet). I set up a load that performs identically with both bullets and shoots to the same point of aim, just in case I’m unable to re-up on one I can use my backup supply of the other.  I bought all of the brass, powder and primers I expected to ever use in this barrel ahead of time (8lbs of powder, looks like I might need another 8lbs). Everything about the gun except the optic I’d settle on was decided before the barrel even arrived. Best of all, the barrel was set up to CRA’s rigorous standards which means it was done perfectly and it was under $400.

Hot Dog Gun before it was even painted. Getting some early long range testing done. Both Vortex Razor 2’s are now replaced with U.S. Optics glass. I just like USO. What can I say, they work for me.

So why am I building a 6XC now? Well Coach and I shoot together. It’s best if we have one set of ballistics DOPE and shoot the exact same load through identical chambers. It’s actually best if we share a gun but I like mine and he likes his. We find that when we can use drop and wind corrections from each other that we win more matches. Duh. If I run a stage and miss 2 of 7 shots on wind, I can tell him what the adjustments would have been and what the wind was for those misses then he can adjust accordingly and pick up those points and vice versa.

So, I’ve got 2 new barrels on the way from CRA, 27″ 6mm 8-twist unprofiled blanks which we’ll have a local gunsmith chamber, thread and profile for us in 6XC with a .267 neck (CRA doesn’t have a 6XC reamer or I’d have them do it). We’ll set them up for zero head space to minimize brass growth and then we’ll use my new ExactShooting.com Custom Collection sizing die to perfectly set the head space and neck tension of our reloaded ammo. We’ll be as close to shooting the same rifle as two guys can possibly get. If you want faster velocities, longer barrel life and one heck of an accurate barrel, you could do a lot worse than to drop Columbia River Arms a line.

Progression of Project Rolling Stone – Mossberg MVP .223

When I picked it up, I got it only because it could take my 20 & 30 round AR-15 magazines and I was in to squirrel shooting and preparing a trip to Cedarville, CA for their annual Squirrel Wars event. I was going to not spend all day loading mags this time and didn’t want to use an AR-15 again. Bolt action seemed better.

I ran over to my closest Big5 Sporting Goods and they had one on the rack with a $50 off sale price. So I snagged that right up. It was a 24″ varmint model and I was happy as a clam, for about 2 days. Within those 2 days I pulled it apart and found it was bedded with plastic, the stock leaned to the right down the barrel channel and action screw torque was unrepeatable. Fine. It’ll shoot. Right?

Iteration 1. Bushnell ET-1040 Mil/Mil and a Harris 6-9″ Swivel bipod w/ podlock.

Well, I tossed on a Bushnell 10x40mm optic, some Burris Signature Series 1″ rings and a bipod and went to the range with some steel cased russian 55gn FMJ. The gun printed nothing inside 1.5″ at 100yrds. Ok, let’s start replacing parts. That’s always the right thing to do. Right? Using better ammo wouldn’t help, obviously. That said, I did start some handloads for it and found it had certain proclivities toward heavy weight bullets and being pushed to primer popping pressures.

Round 2. FIGHT!

So, I found out the Bushnell optic was not tracking consistently. While it was back at Bushnell being replaced (This is a common theme with the 10×40’s. Of 4 of them I’d bought, 3 needed RMA’d) I added a 16×42 fixed power SWFA SS optic and 30mm Burris Signature Series rings. I took that out squirrel shooting and was not impressed. Accuracy with 40-55gn ammo was horrid. With heavier stuff it started performing though. So, change of plans. It’s not a squirrel gun anymore. It’s a match rifle. See, I’d just gotten into a regular local prone long range precision match and needed something inexpensive to shoot there. Well, one trip in and that factory stock was shit-canned. Replaced with an MDT LSS chassis, DPMS PSG-1 pistol grip and a Magpul MOE buttstock. That did really well and I managed to turn in the 2nd highest score ever with a .223 at my regular long range match. That still stands. I haven’t bested it to date.

Not too much time passed and I came into a big bonus so I wanted a major optics upgrade. A quick call to US Optics and I had 2x ST-10’s on the way for various rifles. Epic scopes. Simply wonderful. I took that out with my spotter/best friend, The Disco Tripper, and we turned in some groups on steel. Man that combo could shoot. Running 70gn Berger VLD’s and 75gn Hornady BTHP it was an easy gun to hit long range steel with. I mostly kept those ST-10’s on my bigger guns and used the 16x SWFA optics though. They’re a lot harder to use than an ST-10 but I wanted the extra magnification for the aim-small-miss-small thing.

Once we got to this point my coach started harassing me about trying a bedding job on the chassis. So we grabbed some epoxy and fully bedded the recoil lug and skim bedded the action. I also added a MOE cheek riser to the butt. Instant improvement came from the bedding in that no more flyers plagued me. That settled her ass down nicely and I shot quite a few matches as well as a bunch of informal plinking sessions with the gun. The cheek riser had the rifle as comfortable as if it were injection molded around me. I’ve not yet gotten the rifle in its current form to fit quite that nicely, mostly due to time.

The day I set the 2nd place .223 record, setting up for a 900 yard shot, which I hit. Waiting for my spotter to figure out a set of binoculars.

I have been able to shoot the living piss out of it regardless of whatever else is going on because it’s a .223 and very inexpensive to load for. That’s been a saving grace with this project.

Up on The Grassy Knoll. Stage 2 at Avenal. About to start missing.

It was about the time that my barrel was starting to really age that I also decided to upgrade basically all of my scopes. I started with some more US Optics in the form of an ER-25 for my .308. Not the best choice. It worked great on the big 7mm Remington Magnum (below far left) but not so much on the .308. It was also just too damned big for my safe. No rifle fit in there with the ER-25 on it so I had to bounce that optic and began a long journey of horse trading to end up with what I have now which is more US Optics but these fit in my safe and you’ll see them further down in this article. One thing I was really trying to nail down was parts commonality so I could take parts off of one and put them on another if the occasion arose that it was necessary. My mindset was really into TEOTWAWKI at the time. I’m in a better place now that President Daddy is in the White House.

It wasn’t too long after I’d bounced the larger US Optics ER-25 and an ST-10 in favor of a set of Vortex Razor 2 HD’s. One in 3-18×50 and the other in 4.5-27×56. They are excellent scopes but I hate hate hate pinch screws on turret knobs for exactly the reason that I bounced those Vortex optics. They loosen enough to not adjust when you twist em’ but they still click and it happened multiple times on both turrets of both scopes. Plus they’re heavy as all get out and the 3-18x on the MVP was in MOA because that’s what I could get at the time. All combined I just was not happy. So, I looked around and looked around and finally after almost a year found a US Optics B-17 I could sell the 3-18x Razor and buy. Excellent choice. I guess I’m just a US Optics guy.

I ditched the factory trigger early on and got myself a Jard and a Timney. The Timney spends most time on the rifle. The Jard is special purpose and breaks at just ounces. It’s not a safe trigger for most use cases but it’s brilliant when I’m trying to hit chicken eggs at 500m. The Timney doesn’t have that annoying blade in the middle of it but otherwise is set about the same, 2.5lbs.

All in the family. Upgrades coming rifle by rifle, step by step.

The first Razor 2 to go away was the 4.5-27x Razor II because I had a buyer for it and something on the line to replace it with. I sold it and had enough money left to buy a used US Optics SN3 3.8-22×44 ERGO on a 35mm tube in MOA with a really slick Dragunov style reticle that heavily uses chevrons. It’s a battle ready optic for sure. My coach decided to get into long range prone though and needed a scope so that went on his gun. Now I needed another. Begin the long look for just the right swap.

Black Hole Weapons barrel. Wrong thread patten but that’s a simple fix.

I shot Project Rolling Stone in variations of one form for a good long time. Long enough to burn out the barrel. Truth be told I’d more or less killed that barrel the week I got the gun. I had a bunch of steel cased Russian bulk ammo with bullets that were copper washed steel and started the gun on those. That must have eaten half the barrel life. By the time I’d had around 3K rounds out of it (IIRC, it’s been a while) that barrel just wouldn’t reliably hold the match level accuracy I needed. It was fine for a sportsman, and I gave that barrel away to a sportsman later on, but not for a match long range precision gun. Thing is, only 1 outfit had reportedly made any small ring MVP barrels and they made them shouldered instead of barrel-nutted. I also wanted a particular barrel maker’s barrel. Black Hole Weaponry. Why? Well, their pipes are just too easy to deal with, shoot excellently, clean easily, are inexpensive, stainless and come threaded at no extra charge.

Once I got that barrel situation settled then I wanted to do a little something with the finish. So I got the idea to make it look like a Sonoran coral snake. 3 months of beating on my local Cerakote guy and getting nothing but excuses later I finally got it back, literally hot from the oven and the scale pattern was backward. Fuck! Well, such is life. Only dorks and herpetologists ever notice. What everyone notices is he didn’t finish the last 4 inches of the pipe. Dick! I eventually got it back and had my 26″ pipe at 1:7 twist in Caudle 3-groove polygonal rifled 416R stainless steel. I bought a bunch of 73gn ELD-M projectiles and a ton of new PPU brass and have been swatting steel on the regular with it since.

Sonoran Coral Snake Cerakote

It was such a hassle dealing with the Cerakote guy that I did my .308 barrel with rattle can spray paint and it actually turned out pretty cool despite me not having much experience with this sort of thing. I used the mesh plastic thingy they send barrels in to make the scale pattern and 3 colors of paint with blue painters tape.

Then at some point one of the guys at Primary Arms and another guy from Accuracy Solutions were both interested in how their assorted products would do at my monthly long range prone match. Being a good sport and a bit curious, I set out to find out. I added a Primary Arms 4-14x FFP ACSS HUD/DMR optic and an Accuracy Solutions BipodEXT to the gun. I also switched out the Magpul MOE based butt section for an XLR Industries Tactical stock to gain full adjustability which I wanted for various reasons but mostly because I needed a proper cheek weld with the PA optic on there. The Primary Arms scope works if you trust and use the BDC reticle and did not do well at all when using the mil dots and calculating. This also is predicated on getting the bastard to establish or hold a zero. This isn’t my first rodeo with the PA 4-14×44 FFP. So far every one that’s been to one of my classes has been what I’d call defective in one way or another. Glass is routinely milky, turret click values are wishes at best and inconsistent click to click and across the range, getting one to hold zero is almost as fun as trying to establish a zero. You’ll end up needing a screwdriver to beat the shit out of the scope with after each adjustment. The BipodEXT was brilliant. It put the axis of rotation out in front of the muzzle which increased the lever length enough to make it like shooting from a machine rest. All wiggle was gone! I would recommend the Primary Arms low end line as targets rather than as optics. The PA Platinum line, on the other hand, are fantastic optics that work as advertised, just like the price suggests.

Having finished with testing stuff I didn’t want to use long term and written the appropriate articles, I went back to perfecting the combo and slapped a US Optics B-17 on top. To finish the whole thing I bounced my usual Harris 6-9″ swivel type bipod and put a new AccuTac BR5 into my kit. That’s a beast of a bipod.

Project Rolling Stone in its current form.

I get a lot of strange looks and a lot of people stopping by to make comments from snide to supportive about the rifle and all my rifles for that matter. It’s my toy and I’ll play with it how I like to so I don’t mind when they get snide or chiding. All my match guns are meant to elicit a visceral response. Partly that’s to destabilize my co-competitors mentally so I have a better chance of them doing shitty. Part of it is just for conversation starting. Part of it is, I like these rifles and I like to make them look how I like them to look. I betcha you’ll never find another coral snake gun or another hot dog gun but everyone and their sister has a Hello Kitty AR-15 or a scale pattern on the entirety of their AR-15 or shark teeth, etc… Just because they’re unoriginal repeating pieces of camel poo doesn’t mean I have to be unoriginal.

Project Gabriel in its current form which I call “The Hot Dog Gun”

If you do the math, this gun has cost me a pure fortune. $600 for the base gun, $750 in various stock parts, $5500 in various optics, $40o-ish on triggers, $300 on barrels, $300 on rings and mounts, $10 in muzzle devices (A2 birdcage) and $100 in Cerakote and spray paint. So there you go. I’m about $8,000 in if I’d had to buy each piece at full price. Thankfully, I did a lot of swapping this for that and either reselling or directly trading most of the time so my actual spend on the gun as it sits is closer to $2500US in real money spent.

That said, for $2500 I’ve got a .223 that will easily swat a bad guy or a critter to well beyond the effective range of the bullet it shoots and shoots well under .75MOA. It’s got the best parts on the aftermarket on it without resorting to blatantly overly expensive bits that are just more expensive without being any better. I know a lot of folks with $2500 in an AR-15 that couldn’t shoot a 3/4MOA group to save their skin. I’m pretty happy with what I have here.
