Believe it or not, I know a guy who had a hang fire and turned the gun around to look down the barrel, on two different occasions. He didn't need to have the barrel already pointed at him. The Range Officer (not me, those times) kicked his ass off the range permanently after the 2nd iteration. He reloaded his own ammo,
so who knows what he did there; maybe it only had a primer and no powder.

If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
