Enhanced Analytics Coming To Ballistic_XLR
I’ve been working on a project with Ballistic_XLR to enhance the Statistics page and the Graphs page. Up till now the stats that were being tracked were basically left to velocity tracking and group size tracking. That’s handy for characterizing your barrel and how it behaves relative to cleaning regimes and ammunition performance but doesn’t do anything to help with analyzing where the bullets actually land relative to the intended point of impact and relative to the line of sight. It also doesn’t help to isolate which variables are contributory to imprecision and randomness.
So far I’ve added 2 sets of stats to my working development copy. This set of data is taking shot number within a string into account as the primary point of analysis. When you fire the first shot in a 5-shot string (I had to pick a string size and 5 rounds seemed reasonable) you’ll input the distance up/down and left/right of POA where POI is for each shot in the order that they’re fired. This information is used to track both together and separately the windage and elevation delta from POA. I’ve added average delta, standard deviation, extreme spread and coefficient of variation for wind@shot#.
How is this useful? I shoot competitively with my Mossberg MVP in tactical competition. Strings of fire are anywhere from 1-5 rounds depending on how many targets are on the stage. This means cold-bore shots happen regularly and shot-number-in-string would be useful information to have. I found when testing the enhanced stats page that my cold bore shot on my MVP is always less precise than my 2nd shot or 3rd shot and just as accurate as my 4th shot and more precise than my 5th shot. I’ve also found with some of the existing stats functions that the gun gets into fouling equilibrium between about 100-400 rounds and doesn’t appreciate being shot until it’s been well fouled. This means that if I’m going to need to take a cold bore shot at 700m or better and I can’t fire a fouling shot first I’m going to bring my FFP closer to the target by 100m or so and I don’t want to take any important shots till I’ve dropped a hundred rounds through the bore. I’ll also know that my 2nd shot, if one is needed, will be more accurate than my first shot. I know as well that if I have to get up to shot 5 that I’m going to have to wait a few minutes for the barrel to cool.
The greater overall scheme for the stats page is for it to show relationships between hits and each of the variables, wind, temperature of air, temperature of ammo, air density, muzzle velocity, shot number, barrel fouling, etc… I want you to be able to use the graphs and statistics to do your handloading and get ammo that performs even better. It’ll already help you do ladder tests and OCW tests and fouling tracking. What I want is to provide a multi-dimensional mapping of variables to performance which users will be able to use to find areas that can improve the performance of their weapon system. I want it to account not just for the performance of the weapon system but also to characterize the shooter and help them improve themselves.
Look for the enhanced statistics and graphs coming up in Version 7.9. Release is expected within a week or so. If you’re a professional statistician and would like to help please reach out to me by email. Ballisticxlr at gmail dot com.
