Well sometimes the trap can get deformed. If it gets really dinged up there's no telling what the result could be.
I shot at a range for .22LR and pistols where the whole back wall was some kind of metal plate from ceiling to a sand floor. The metal was at a 45 degree angle so pretty much as long as you shot 'down range' you'd be okay. Well somebody brought in a high power rifle and before anyone stopped him fired 3 rounds that made nice little nickel sized craters in the smooth sloping metal. A round hitting the crater just might come back at you. I'm not sure what they ever did about it powers that be weren't pleased about their backstop getting dinged up like that.
