The problem with braked rifles is that their bark is literally worse than their bite. Recoil is an exhilarating, and enjoyable part of shooting powerful rifles, but redirecting the the muzzle blast back towards and out to the sides of the shooter is a flinch in the making. I challenge you to sit on the bench next to a .30-378 shooter, who is using a brake equipped rifle, and shoot a decent group. When he fires, you can feel the pressure wave hit you, not just hear it. That will disturb your aim to the extent that you'll give up in disgust and wait until he's finished.
Brakes have their place, which is on .50s, Cheytacs, and such. These rifles cannot be reasonably shot without a brake, but their long range capability suggest its unlikely they would be used on a standard rifle range where shooters were positioned close together.
I don't understand why anyone would use a brake while hunting. Rather than a brake, you need less gun if recoil is a problem. Recoil is best addressed through a quality recoil pad, proper gun fit, and the correct shooting technique. If it hurts, something is wrong, or the gun is too big for you. Either way, an adjustment must be made, perhaps to the LOP, perhaps to the quality of the recoil pad, perhaps to you shooting technique, but to trade flinch inducing recoil for flinch inducing blast seems counter productive. To continue using a rifle that is poorly set up for you, or to continue using a poor shooting technique, because you've traded one type of waste energy for another, will do little for your practical field marksmanship. Of course when shooting from the bench, a rifle can shoot tolerable groups even if the shooter is standing on his head, as he, for the most part, is removed from the equation.
