Another flashy one was the old AMT Automag .22 WMR. Man, that sucker was a hotrod. Didn't shoot it much, the concussion was literally shaking the fillings out of my teeth. Still it was impressive. Ended up using 30db NRR rated muffs ALONG WITH those little foam earplugs that are rated at 31. It was still too loud for my taste. Thought it was neat the way it made the armor ring at the back of the range. Kind of regret getting rid of that thing. Had no real purpose, but was an incredible noise maker.
