Put quite a few 40's in my new M&P 10 past few days getting the sights right. Picked up a stack cheap from guys backing away these days. Would have cost more to shoot that many 10's and been a bit of a work out too. At close range, 10 yards or less, they hit the same so it's effective feed back. Farther back I don't remember exactly with the Glock. A 12" gong is a hit either way though. Common sense and basic logic get people hurt all the time, but this practice seems harmless enough anecdotally at least. So many idiots on You Tube telling us to try it at home. How rare is that?
