Spanky: You have that right to believe the way you do. But I will disagree with you when you say they have no benefit to a hunter. To me they have a great benefit. Yes they are loud for the shooter, but muzzle jump is reduced or eliminated, to the point the shooter can watch the bullet strike. That is important.
Second the sound issue, the sound is channeled to the rear, making it harder for the animal to pinpoint where the sound came from. A missed animal will stand there looking around trying to decide where the noise came from giving the hunter the chance for a corrected second shot.
As for the range, everyone should have hearing protection on or they should not be there, period.
My partner has a .50 cal BMG. He has the Howitzer style brake on it. We will be sitting shooting it, down at the end where no one else is set up. A new family moves in during a clear where we are downrange replacing targets. When we return I try and convince them they need to move. No they don't want to hear it. Norm makes his first shot. The shockwave hits me, but I am expecting it. The new group was not, and they get rocked to their socks. Suddenly they decide it's time to move. Yet Norm felt no recoil at all. When that 750gr bullet hit the back stop, everything within five feet was obliterated.
