Lately I have found myself flinching a bit. I couldn't figure out why for quite a while because I'm not scared of any of my guns. I was even doing it while shooting my 5.56 which is ridiculous the gun weighs in at 11 pounds and has a muzzle brake. One day I decided to put ear plugs in along with my ear muffs...wouldn't you know it I stopped flinching. I guess I am more noise sensitive than I realized. The way they have our shooting house set up doesn't help. They have it completely covered with metal roofing and no insulation inside. At the shot it sounds like your shooting in a tin can.
I was wondering if anyone else has noticed this issue?
