Lately my wife has been helping me get range ready,She is a nurse and there for a medical professional,I don't question her advice after 48 yrs.Like everyone else first plugs,then muffs. then a 12 gal kitchen size garbage bag over my head and taped tightly around my neck with Gorilla tape. The sound reuction is incredible, but after the first string of 5 shots ,I start to tire out and get a headache. She says I don't need a Dr. just keep shooting and then I can take a long nap.Talk to you later....Maybe.
