We have a gun club here like that. If you don't shoot a deer rifle, skeet gun or target rifle you are a lowlife to them. Funny though that there is always a ton of assault weapon brass on the ground when I would go up there.... Anyway, one day the guy who CONTRACTS to do bore sighting came out to throw me grief for shooting a semi. A fairly expensive one at that, but it was an assault weapon none the less. I was not shooting rapind fire, not throwing my brass on other shooters, or doing anything that would be considered bad form or unsafe. But it was an assault weapon and the nature of the weapon made me evil.
So he came out and read me the riot act about how people like me give all "other" gun owners a bad name. He also said people like me should not be allowed to shoot up there and I should leave. After a total of 5 rounds that day, I had had enough. I went to the club house and explained what happened and got my money back.
I did not get really mad while I was there, I got mad later. While I was there I stuck to my mantra. "Don't get mad, get even."
So it took me a while, but the next time I went up I made sure I took a bolt gun. I got to the little building he had on the range where he does his zeroing and ask if he minded if I set up right next to him. He didn't (and luckily there were no other shooters around, otherwise I would have felt badly) and so I did. The 4lb muzzle brake stuck out past the end of the building, and right in front of his little window about a foot. The first shot caused a few alarmed screams from inside. By the time they recovered I had the second shot off. That caused more screams and the door came flying open and he came out asking rather loudly what was going on just as shot three went down range. Poor ol' guy was one who thought that just cause he was at a range that he didn't need ear plugs when he was sheltered in his little building (at the time I was completely unaware of this, but I don't feel badly about it at all). And he didn't have them in when the third .50 cal round went down range from under the covered firing line.
He was not happy, and recognized me finally. That made him even less happy. I was none to humble when he started to read me the riot act again and I pointed out to him that the rifle was not an assault weapon, he told me to set up there and he was responsible for his own hearing protection.
I left as persona non-grata at Holiday Gun Club, but I not only got even for his piss poor treatment of me and the other "evil" gun owners, but I also made the point to the owner that this guy was costing him a bunch of business for his treatment of younger people who shoot modern guns. And their business sucks anyway, I wonder why.
My point here is that it is not always the best idea to get into a battle of wits and yelling with someone who is half equiped for such a fight. But listen to them and they are bound to give you something that will allow you to have a bit of fun with them.
