Personaly I do not like M/B's. One day at the range my brother in law touched off a round fromhis .223 T/C pistol with aM/B before I got my plugs in. It hurt so bad I can't believe I didn't lose my hearing in that ear.[:@]I shoot my 7mm Mags all day long at the range and never felt the need for one and besides that, when hunting, I won't even pull my hood up over my earslet alone use ear plugs for fear of impeading my hearing. Just my 2 cents
