Be warned about the extra noise mentioned by others. I just started centerfire shooting late last year. I purchased decent earplugs for me to use at the range, didn't like the bulk of the ear muffs. Second day at the range, I was on the right end bench of the 50 yard line, and there was a guy with some ported/breaked canon on the left end of the 100 yard line, not a 50 BMG. There was about 50ft between us. It took one shot from his gun to damage the hearing in my right ear permanently. The shockwave was so severe I could feel it go from the right side of my head to the left side. Needless to say, I never go to the range without ear muffs, and if there is anyone shooting ported/breaked rifles, I step back from the firing line and wait till they are done. Porting and muzzle breaks are very inconsiderate configurations to your fellow shooters at the range, as well as being potentially dangerous to your fellow shooters hearing.
