How To Use Ballistic_XLR: Table 10
I’ll cut the story a tad short and note that the Table 10 tab is used exactly the same way Table 100 is used. The reasons for using Table 10 instead of table 100 is when you’re shooting at a target at such long range that the dope changes so quickly that range estimation or interpolation errors that are very small can cause a miss or to strike the target in a non-critical area. In general beyond 400m I would recommend using the Table 10 tab. The other reason is that Table 100 is limited to 1800m due to available space while Table 10 goes out to 2490m which is close to being a practical limit on what even the most advanced shoulder fired precision rifles are capable of. Yes you can reach farther than that but almost nobody is able to shoot anything usefully small at such ranges. Even with a .1MOA rifle you’re looking at a target with a radius of 30 inches as a useful minimum. Well if your target is 5 feet across you should probably be using something more than shoulder fired small arms to destroy it. The primary reason for even creating a 10 meter/yard increment table was to eliminate the need for significant interpolation when shooting at extreme long range, not simply to increase the range you can shoot at. As long as your weather and weapon conditions are stable you’ll be able to stay “on-tab” (as I call it) and not have to do much in the way of interpolating and that’s the benefit in the 10m tab. If you’re shooting at beyond 400m I would say that Table 10 is the best option.
