I'm planning on building a rifle for deer and elk hunting. I am having a little trouble on choosing a caliber. I am not planning on bench shooting comptetivly. I'm not a wildcat cartridge guy but would consider one. I was leaning towards a .300 win mag, but I don't want to have a muzzel brake on the gun. Maybe I don't need to go that big... I'm thinking 0-800 yards or so. What are some of your thoughts and why. Thanks for the advice.
