45ACP, 40S&W, .357SIG, 9mm are suitable for game weighing less than 50 lbs. Taking larger games is possible but unethical.500 or Below -- Small game weighing less than 50 lbs
501 to 900 -- Medium game with a body weight of 50 to 300 lbs (e.g., deer, black bear and caribou)
901 to 1500 -- Large and heavy, but non-dangerous game weighing from 300 to 2000 lbs (e.g., elk, moose, African plains game, bison, etc)
1501 or Above -- Dangerous game of any weight (including, for example, big cats)
It only registers 441 with a 255 grain 45 caliber bullet traveling at 960 fps which is velocity at the muzzle not down range.When I used this calculator I got 501-900 = Medium game, using calculations of Buffalo Bore 255+P, 45ACP ammo.
Hunting deer at 100 yards with a handgun chambered in 45ACP is folly.But with a 45ACP using the right ammo, you would be at roughly. 400lbs energy at 100 yards.
