The black powder will go off just from the compression of the threads. One flake is said to be enough. I’ve seen some interesting photos during Hazmat training.

I had a Sharps reproduction. It was not a cartridge rifle. You lowered the breech block, dropped in the ball or bullet poured in powder behind it all, raised the block, capped it and fired.

Well I had been a little careless with the powder. There must have been a fair amount still om the outside of the action. When it fired just enough fire made it around the breech to set the powder on the outside off.

Burned me a little. I was much more careful. It actually had a blade of metal to help seal the action but it wasn’t perfect.

Well that problem is easily solved -- just get some Symtex at the local Home Depot. ;>))
