I have a range about 2 miles from here. It is unsupervised and I have never seen much of anything done wrong with the exception of shooting without earplugs. I figure its their ears except when they have kids with them without ear plugs as well. I usually give the kids earplugs. The parents are always thankful although I cant imagine taking a kid anywhere near a range without their ears plugged and muffed.
Now I have seen some **** poor shots and a lot of windy shooters..lol. Some of the example of "marksmanship" is downright hilarious. Seeing guys trying to dial in scopes shooting one round after another without ever letting the barrel cool...the list is endless.. Makes for good entertainment and a boatload of free brass for me.
