The redirection of the sound and the blast is my biggest problem with a muzzle break. The shooter gets a big advantage, not the rest of the guys around or behind him. When hunting DG and a hunter uses a muzzle break, the PH usually suffers. Even if the PH wears ear protection the shock waves will stun him and he is temporary disorientated, this at a time when the he must be ready to provide back up in a maybe potentially dangerous situation.

Personally I will never use a muzzle break, if I cannot handle the recoil I will make the riffle heavier or reduce the load.
