I have a Winchester Trapper carbine in .45 Colt. I would like to use it while stalking deer in the upstate. I’ve never hunted with this gun. I bought it new about 15 years ago for Cowboy Action but never used it. It’s really been a safe queen with an occasional range trip. I was looking at some Buffalo Bore 300 gr. flat point +P for hunting. Are these too hot for this gun? I know my Black Hawk can Handel them.
