I was out at the range on Friday. I was at bench station 15 (50yd/100yd). Stations 10 thru 13 (100yd only) were filled as was 16(50yd only). Stations 14(100 yd only) and 17(50yd only) were open. Stations 18 and 19 are 100 yard steel targets and also open. I was shooting a 7.62 x 39mm bolt action, elbows and sling at 50yards at three separate targets basically hitting within 2-1/2" of the bullseye so the rest of my target board was clean. The guy at station 12 was shooting 100 yards rimfire target shots. The guy at station 13 was shooting an AR 5.56NATO at 100yards. The next thing we know, the guy at station 12 is overheard telling the guy at 13 that he is spraying his AR shots onto the No. 12 target. The guy at 13 apologizes. I stepped away from my station to take a phone call. When I got back I noticed the guy at 13 shooting offhand. I set my rifle up for my second of three targets and when I looked through my scope there were several stray 5.56 bullet holes peppering what was my clean target. The guy at station 13 then asked me where can he shoot the steel targets? I said only at stations 18 and 19. You can guess the rest as to how my target got peppered by Mr. No. 13 AR. He eventually admitted shooting across the field and apologized. At first, I didn't know what to think but turns out, the guys lost his mother years ago and his father, a Marine just died. Both parents died in September so he was feeling really down. His dad left him several rifles that he wasn't too familiar with and brought them to the range to shoot. This day was sort of his re-connection to his dad. His ability to follow the rules was horrendous and his ability to hit targets was worse. He left for the day before the rangers noticed what he was doing. I am hoping the guy gets a lecture and lesson on guns from somebody but I felt this wasn't the day nor time. I offered my sympathies for his loss, wished him well and said I hope to see him again. We shook hands and I can see in his eyes he needed somebody to listen to him.
