Most of my biggest hunting/shooting bs stories came from my Montana Hunter's Ed instructors... He was giving a "course" on muzzleloaders, and had a rusted out, piece of junk in-line with a broken off triggerguard for the demo.. When he got to muzzleloader "safety", he told us if the gun would not go off, the only safe thing to do was to throw it in a lake or other body of water... That sounds like a good idea. Don't ask me why he wouldn't just unscrew the breech plug and ram the charge out. His preferred method of cleaning this muzzleloader was to run a nice hot bath, and clean it while he took a bath. Seriously.
