Oh boy talk about a topic right in my wheel house law enforcement. Bolt gun versus a gas gun. Only way I’d ever recommend a gas gun is in a hostage rescue situation, in other words close quarter battle.
Anything past 50 yards, bolt action rifle all the way. I think if given the opportunity and outside of comfort zone training 200 yards plus, a few agencies along our southern border would support bolt action rifles.
I better stop here before I get carried away with my reply
Am I able to download the podcasts to listen offline?
What’s new in the 4th Ed. of Applied Ballistics for Long Range shooting. I have previous editions and all your other books.
Also, as much as I love your publications, the fact that they are missing an index is maddening. My understanding is that you can even use AI to construct one. Even an index, that was available to download for subscribers of TSOA, would be appreciated. 🙂
Hello, Thank you for your support. There is only one difference between Applied Ballistics for Long Range Shooting 3rd and 4th editions. The 3rd edition had a CD for the “Point Mass Solver” but the 4th edition now has a link to download the software instead of a CD. Bryan has discussed putting an index in books but has decided not to. We apologize for the inconvenience.
hello. Bryan. the torque that you spoke about with the botail talk. is that referenced with the magnus moment? that is set up by the magnus force?
I am a relatively new member, so if this has been covered elsewhere already, please point me to it! Can you discuss the effect of bullet jump sensitivity on short range (~100 yd) dispersion) and how it can be affected by the gas flow environment immediately upon the bullet uncorking from the muzzle. I think I have observed that, especially on short AR’s (i.e. 11.5″ 5.56 barrels), the muzzle device, the installation of the muzzle device (e.g. if there is a gap between the actual crown and the first port of the brake or beginning of the flash hider), and possibly the shape of the suppressor’s first blast chamber seem to have a dramatic effect on the groups I see with SOME (but not all) heavy for caliber (73-77gr) loads that should ostensibly be stabilized.
e.g. I have an 11.5 KAC SR-15 that shoots everything I feed it in the 55-69gr range very well (as far as ARs go, i.e. .8-2 MOA 10 shot groups), but with some 75 or 77gr loads that should on paper be stabilized, if I have e.g. a surefire 4 prong (which has a gap between the barrel crown and the opening to the tines when installed) and an RC2 either on or off, I observe unusually bad groups (3-4 MOA with some 77gr match loads that normally shoot ~1-1.5 MOA 10 shot groups with longer barrels) and sometimes egregious ~6 MOA fliers. Some 77 gr loads don’t do this though. I am fairly certain this is not the result of baffle striking. Assuming there is no physical contact between the bullet and muzzle device(s) upon uncorking, what might explain this?
Thank you, by the way!
