Well, the public range near me is attended by a state employee who is usually a Fish & Game cop working off season. That keeps most of the idjits at bay.
So far this year, there is the old guy who comes out with a nice older Garand, fires maybe 1 clip through it (Yes, CLIP, Garands have clips, not mags, *ping* and all that)- but he is at the rane maybe 4 hours to fire those 8 shots, and he spends all his time walking up and down the firing line asking people a lot of personal questions, do you belong to the NRA, stuff like that.
There is the guy who was brass ratting- Hey, I'm a brass rat, but I believe as long as someone is at their lane, they own their brass!- Anyway, this guy was literally scooping up brass as it is ejected from the gun. It was annoying this shooter, who changed over to a Mosin-Nagant with a 16.25" barrel and lit off a couple shots. The brass rat clutched his ears and staggered back, cussing and fuming.
Then there are the guys who show up with a nice AR and set up ten yard targets and proceed to hold a nice 12" group at ten yards and brag about how they bought the cryogenic steel heavy barrel with flutes and stinger missiles and a laser sight that shoots down satellites and how uber-Awesome the rifle is.
The standard response from the RO is, "If any rifle I owned shot like that I'd send it back to the factory."
Then there's the carload of early 20-somethings that always have at least one AK and a few pistols that just can't stop bumpfiring. Or rapid fire mag dumps in the pistols. While giggling, usually.
Let's see, there's the "Most Powerful Handload In The World" guy.
There's the "Anything less than a .50 Deagle is for wusses and pussified men" guy.
There's the guy who shows up and runs 500 patches through his gun between shots because he's "breaking in" a new barrel- and lets the patches just drop on the ground and blow around.
BEST ANECDOTE EVAR:
True Story:
I have a Savage-Springfield 120 .22 single shot rifle I got cheap. It had no rear sight. I stuck a cheap BSA riflescope on it on some freebie rings I got and went to site it in, but forgot my binoculars. It's hard to see a .22 hole in a target at 50 yards with no binocs, especially since the scope wasn't even boresighted, just stuck on, so I moved the target holder to the pistol line at 7 yards for starters to get it on paper. Well, the scope was so far off I was getting frustrated, I'd got there 20 minutes before closing, and I still hadn't gotten it in the 10-ring yet. When you arethat close it takes a lot of clicks to move your POI!
Anyway, the RO calls last shots, I took the last shot, and was just outside the 10-ring. Frustrated, I put the rifle down and someone made a comment about how the safest place on the range was behind my target. So I took my FAL bayonet I had in my shooters bag and whipped it at the target. It stuck low and in the bull, and the entire target stand fell over on the ground. (It was a home-made jobbie out of scrap lumber).
Well, after the laughter died down, the RO gently reminded me it was a SHOOTING range not a knife range.
