because when I shoot I like to shoot more than a couple rounds I tend to empty a box a day when I shoot. And with the brake I can do that with out my sholder hurting. And my wife loves to shoot with me and she only ways 115lbs and it makes it easier on her.
Hey to each their own. Personally I've got one on my .50 BMG that really has pissed off a few people with it's blast. Not that the .308 will be that bad ,but you better be aware of it when shooting close to others. They can be hell on your ears.
I've know more then my share of professional hunters in Africa that that will not allow their clients to hunt with muzzel brakes.
