Carbine Drop Charts

Here I will post hold over/under charts for common carbine calibers. The point here is so that users can stretch the range on SBRs, submachine guns, pistols, and carbines. For more information on muzzle velocities out of various barrel lengths, check out Ballistics By The Inch. Of course, I modeled the trajectories in Sendit Ballistics.

9mm, 16″ Barrel

This chart is for a 124gr 9mm fired out of a 16″ barrel. The zero is 25, with re-zero at 80 meters.

Sendit Ballistics

Check out Sendit Ballistics for iOS if you are interested in an accurate, simple bullet trajectory calculator. I keep an updated page on the app here. The app is so accurate because it models the most important 3 degrees of freedom with painstaking detail. The app is designed for the field user, with a simple interface, range card mode, low light mode, and rapid corrections with minimal information. It is free to 400 meters, and only $4.99 to infinity.

Mountain Guerrilla: Drill-Building for Skill-Building

Balance in training is key. You should drill fundamentals and incorporate more realistic and force-on-force work. Be wary of trainers that suggest ditching square ranges. Likewise, understand the square range is crawl/walk; you need further drills for the run phase.

INTRO:

It’s become something of a cliché, in the training world, to point out that “Life isn’t a square range!” The implication—and sometimes it’s not even implied, but violently explicit—being that if you’re doing fundamentals work with your weapons, you’re going to die, because your training isn’t “real” enough. I’ve always found this ironic, since in my experience, the ability to actually hit what the fuck I was shooting at, on demand, as many times as I needed to shoot it, was THE defining factor in success in a gunfight. Where did I learn to do that? On the fucking “square range!” Admittedly, they were actually, usually rectangular, but…
