Reminded me of three "idiots" in Arizona many years ago.
To set the scene, Open pit Copper mines use a LOT of explosives and it is stored in bunkers away from the site. Now the bunker is secured by a locked steel door marked appropriately.
These three idiots had an 03 springfield and some AP ammo that they wanted to test. Guess what they used as a target!

Two of them got behind a large rock while the third "tested" his ammo on the door. The bunker contained FIVE tons of dynamite and another five tons of blasting powder.
The shooter had an arm blown off, one of the others was reduced to incoherence from the shock, and the third was only deafend.
