I stopped by the indoor range earlier with my sister because she'd never shot a gun before and wanted to try. As we were shooting, a younger guy came in and set up. A few minutes later he opens up with an AR-15 just as quickly as he can pull the trigger. As soon as he started shooting, everyone on the line and inside the store stopped what they were doing and were staring in disbelief. As the range officer was coming in I heard one last shot and saw that my target had a big hole in it. He shot my target, which was 2-3 stalls down from him! Range management quickly came in and put a stop to the shenanigans, and the unauthorized caliber. He was not an issue after that, but I wasn't too happy that he shot my target. What's wrong with people?
