Encrepete,
actually my buddy who suffered major damage always wears muffs and plugs when at the range. Something I have always done also. His damage was done from shooting at game only without protection. He also owns a .270 browning Abolt that has the Boss on it. I have personally seen that rifle shoot onder 7/16" several times once he found the sweet spot. Not saying that the Boss is not effective, it works great although it does it while destroying hearing. Hey some people smoke and won't believe it will harm them. Enjoy yourself
