Shot a lot of rea bucks in Germany with the M-1 carbine. But still wouldn't recommend it. Couple of problems. The military ammo is all FMJ, penetrate pretty good but awful weak. If I were to use it, I'd handload it with no more than a 125 gr soft point bullet. Then of course there's alway's gonna be someone that want's to shoot it a little farther, the old buck of a life time story or the I'm only human bit.
There are so many suitable cartridge's out there with little recoil that there's no reason to use a 30 carbine. Hell, for handleing qualities and gentle recoil, find an old 600 Rem and have a 6.5x54 barrel put on it. Maybe even a 250 Savage?
