Just got back from the range and some guy three table's down had a .375 with a muzzle break. I am very serious when I say that those things can damage the ears of people next to them, even if we are wearing hearing protection. I had to back off and wait until this dude finished. I should have offered to shoot the gun with him standing 20 feet to the side of it. Seriously lethal to everyone BUT the shooter. It really made a huge impact on me and I will forever take inventory of what others are shooting around me.
