I have been using muzzle brakes ever since I had a 5 1/2 lb 300 RUM built in '95 - only used for hunting - ready for new barrel. All of my other mountain rifles have brakes except for 7 STW Blaser. Fortunately still have excelllent hearing (audiogram confirmed) even though do not use hearing protection in the field (I do not recommend this). At the bench I use double hearing protection - plugs (34 dbl reduction) under muffs. Len's recommendation above is excellent advice. I use hearing protection for almost everything else - lawn mower, power saw, leaf blower, grinding wheel etc.
