If you put like 1 ear plug in your left ear (unless you are left handed) it would be fine. You can normaly stick 1 plug in pretty quickly.I shot a 270 with a muzzle brake and it was WAY too loud. You're shoulder would be fine, but you wouldn't be able to hear much for at least a few days. I injured my shoulder a few years ago, and I just suck with my 30-30 that year.
