I had a DQ this last weekend during my second USPSA match on the second stage after fumbling through it (was a long, 32 rd stage with 2 activators and 7 positions to shoot from). Stupidly, I pulled the trigger on a live round during ulsc. I immediately looked at the RO (who was the range director) and said "That's a DQ." "Yup." Fortunately, it was in a safe direction and pointed down toward the berm. The RO was very cool about it since he understood that I had made a massive brain fart and knew the rules otherwise. Unfortunately for me, it was an extremely embarrassing display of not carefully following directions. I did stick around for the entire match to help paste targets, watch other shooters, and generally reflect on the massive mistake I had made. Still had a good time, but I'll definitely be slowing things way way down during the ulsc. Doesn't help that I hadn't shot a match in a few months, but still not an excuse. I'll be back next weekend for some steel challenge.
