Buy a quality gun to run "Ruger Only" Colt loads and don't look back. Coming out of a carbine/rifle you're carrying more KE than the beloved 30-30 out a pistol cartridge.......
I figure a 30-30 round of 150 gr moving 2400 fps at the muzzle = 360
I figure a 45 colt round of 315 gr moving 1700 fps out of a rifle - 535
I figure the same 45 colt round moving 1400 out of a handgun = 441
All figured weight x velocity / 1000
I'm a little partial though.
