Federal 45 Acp round destroys 1911.

I was shooting with some family this weekend and i let a 15 yr old family member fire the weapon and i was loading a clip and his mother was watching him. He fired screamed and dropped the gun. A Federal round exploded inside the chamber sent shrapnel out the ejection port into his face cutting his face and eyebrow chipping his glasses the cuts weren't to deep but there was a lot of blood. We are debating what to do abut the situation,Federal is having me send in the remainder of the ammo to get it tested but honestly all they are doing is sending me more ammo (which honestly after what happened i don't want any more ammo from them). Anyone have any advice or heard of this happening to anyone else?
