By definition any caliber that breaks 1140 FPS at an ambient temp of 60 degrees f is super sonic thus IMHO high velocity. If a 230 grain military ball 45ACP traveling at 850 FPS is low velocity and a .117 caliber air rifle pellet traveling at 1200 FPS is high velocity.
Which one would ya rather get hit with ?;O)
It's all subject to each persons views as we shall now discover here on this thread........:o) Spectr17 may weigh in and correct /help me. Stay Safe !
If I'm too slow to start getting some book learning,I can always revert to experience and stay dumb and happy,it's carried me this far.
One thing I do know about BB guns and .45 ACP,if hunting rabbits with a cheap Crossman BB gun,a close head shot is nearly mandatory to stop the critter and with the .45 ACP in a 1911 or 1917 model Army revolver,(or even a .357),a head shot is mandatory if you want much left for dinner.
See,some things even I can figure out,I'm maybe not completely stupid.HeHe. :)
When I got my first .17 Remington a buddy helped me set the scope.Even as a kid this guy was the best long shooter I've ever seen.I wasn't going to see my friend for a long time after that day and he had never used a .17 so we went looking for a coyote and he was going to do the shooting.We really didn't know if that needle bullet would do a job on a coyote at the time.This was long enough back that the state had a bounty on ears along with selling the pelts.
Anyhow,my buddy got a shot at a coyote headed away from us and it put the critter right down.We couldn't find an entry or exit hole even after skinning him.
I cut into the critter to see what the deal was and found that my friend had made a perfect...well...not bullseye but browneye and the little bullet didn't carry through to exit.Best shot for the pelt I've ever seen.
Hoo boy,I'd best shut up,this dope the Doc's got me on has me rattleing.He.Sure has brought back a lot of fond memories,though.
