It has been a decade or more (will see if I can dig up the story) but a local range had a incident like that except when the brass went down her shirt she started jumping around waving the gun and ended up shooting her boyfriend in the head DRT.
This goes to show that there entirely is such a thing as "too much gun". Whenever I teach someone new shooting for the first time, I make sure to use nothing except pipsqueak loads. And in revolvers too. There is nothing that will frighten away a newbie more than inducing them to shit their pants when they pull a trigger.
There is a video posted a while back that showed some douchebag making his unsuspecting girlfriend fire off a regular load in a .500 S&W Mag just for shits and giggles. I was not laughing. At all. If you are curious. That kind of nonsense gives us gunnies a bad name.
