I have used muzzle brakes while hunting and I will never do so again! For some reason that shot oppurtunity always comes when you are busy rearranging your hearing protection. That said I do like to have a muzzle brake on the big bores while developing a load. Shooting 40-50rnds of anything over .458 from the bench is liable to make you flinch at the end no matter how well you normally shoot your big bore. But other than that I don't really use them or want to use them.
