I've still got the mangled barrel of my first shotgun. Dad double-charged a round. Luckily for everyone, he was shooting and no-one was hurt. I shoot left-handed. A piece of shrapnel that came off the barrel would have removed the right side of my head had I been shooting.

Ouch!
But nothing compares to what happened here:

USS Iowa

And in her glory days!

Broadside!
