In the excitement of shooting at game, you likely won't even hear it. The suggestion that you will be deaf for hours if you shoot it once is absolute nonsense. The major noise impact is parallel with the muzzle, so unless you have a really weird way of holding your rifles
...In the excitement of a fist fight one probly wont feel his nose get broken either, but its broken just the same, damage done regardless.
i am not a muzzle break fan either, i recently had one removed from a rifle of mine and its a remarkable difference. it went from a safe space-filler, to a take-everywhere gun just like that.
