Loaded or Not
I'm the guy who had the BC Game regs make the statement about ML arms NOT being "loaded" if unprimed, percussion or flint. It is in compliance with federal and provincial laws, which cannot weaken the former.
Yes, it can happen that a flinter can fire if the flint is snapped on an empty pan, but if the shooter had a clue, he'd have a frizzen cover for safety and to keep it's face dry in wet weather. Nothing is fool proof in the hands of a fool.
As for a percussion gun, short of dropping it into a fire or being incredibly stupid with smoking materials, I fail to see how it could fire. That's like expecting a .30-'06 round to fire without a primer in place. If the priming compound has stuck to the nipple, a probe with a vent pick will remove it.
Again, the adage of nothing being foolproof in the hands of a fool applies.
I also hunt occasionally with a '63 Sharps percussion rifle. I consulted with the local CO and asked if he was familiar with the law re: flint and percussion rifles. Then I asked his attitude towards me having a paper round in the chamber with the nipple unprimed.
After a moment, he said that it would fall into the same category as far as common sense would indicate.
If you're unfamiliar with such ammo, you may or may not be able to drop the cartridge out of the chamber as there is no extractor and nothing to grab if there was.
If you have used the 'cigar cutter' on the gas check to shear off the end of the paper cartridge,you now have loose powder (a safety hazard) and maybe a ball stuck in the barrel; a potentially dangerous situation if not removed immediately, which requires a cleaning rod.
Loading the cylinder(s) of a cap & ball revolver and transporting them separately to the range would seem to make sense for those who live in cold climates. Transporting a capped cylinder under any conditions is courting an accident.
ML and BP firearms in general require that the user be a pretty bright bulb and relearn what was once common knowledge.
