I have put muzzle brakes
on four rifles and found them to substantially reduce recoil. The difference is more pronounced in my .300 than it is in my 6-284. They are damn loud too. I always shoot with hearing protection, so no problem at the range, but my ears do ring when I fire a shot while hunting. My ears also ring when I fire a shot without protection from a rifle without a brake. Well worth it to me, especially in the magnum calibers.
