I have hunted a great deal with the 257wby,7mmstw and 300ultramag and have no problems with noise with any of the three.I do not wear ear plugs while hunting and according to my annual hearing tests my hearing is just as good as it was when I hired on at my present job 23 years ago.However one shot with a boss equipped 7mmremmag rifle had my ears ringing for a couple of hours.I will never own another muzzle brake again.
