Good links, lancaster.

I feel compelled to comment here on one of the gun loads used, the muzzleloading gun with 2 caps.

Pyrodex, now that was a funny clip. The big gun the fellow loaded with Pyrodex with the double musket caps for ignition, was originally a flintlock and was converted to use caps to ignite the pan powder.

He should have put a small amount of real black powder down first, then the rest of the charge could be the phony powder.
due to the 17% composition of chlorates in Pyrodex, it's fouling is very corrosive.

Too, Pyrodex has a very much higher ignition temperature requirement than real black powder and that is why, with the 1/2-assed conversion to cap-lock, the gun missed fire so many times. He put more and more powder into the pan, but no flame was directed into the vent hole to ignite the phony powder. For the same reason, flint-lock guns loaded with Pyrodex do not generally manifest their charge without 'salting' the main charge with black powder loaded first as a starting charge, just the same as the older BIG cannon use today, to set off the main charges.
