I haven't kept count of the number of times someone has tried to shoot me at the range. Once, though, sticks in my mind. I was at the silhouette range, and to mu right, a couple of tacticool boys were shooting... well, everything. Including a hand cannon in .50 AE Express. They were having a HARD time cycling the action on that cannon, but were keeping it in a safe direction. Then the range officer came over, and showed them how to do it more easily by supporting the gun on their stomach. With a loaded magazine and one in the chamber. Having them point it STRAIGHT down the line to their left.
I tried to push my stool back out of the way, but since the concrete there is grooved, the legs caught, and I pushed myself over flat on my back. And they looked at me like I was the idiot.
