Yeah, that was a scary one. I'm glad it turned out alright. I'm also glad she came back to continue shooting. Yes, she messed up, but she got back on the horse.
I've had it happen to me as well. I frequently shoot at a commercial range/club and we get all kinds. The RO's are all very good but can't be everywhere at once. I tend to pack up and leave if it gets too hairy.
