A note on this: when I was in boy scouts, I watched a guy in full Revolutionary War uniform get a chunk of his hand blown off because someone left the worm in the cannon they were firing as part of a demonstration

Saw a dude in Napoleonic garb accidentally blow a load of black powder from a cannon into his face at a museum once. It was not pretty.

This guy noticed it was still in there after the fuse was lit and went to grab the pole to yank it out, but he was tragically too late

metal

Tally ho, is it?

Did they cut his arm off at the elbow, or do they not take reenactment seriously?
