All good to know! Thanks!
I'm going to try to make a thinner Enfield-type cartridge with the bullet reversed, facing the powder chamber. I made some simplified reversed-bullet cartridges, and the paper with lubricant on the bullet was too thick, so I couldn't get it started in the muzzle to tear off/ snap off the empty powder cylinder.
I've got some better paper, I hope! I'll make up a bunch of those types with the reversed NC "Nesler" ball and dip them in tallow or 3 parts tallow to 1 part beeswax...
Then, I'm also going to make some "central pillar" type cartridges with the NC "Nesler." For those, I'll roll the paper around the forming rod/ mandrel with the Nesler bullet on the flat side such that the rolled paper covers the ostensibly "collapsing skirt" if such it really is, and tie that area with a linen string. That way the paper part will trail behind the exposed lead slug. It'll kind of/ sort of look a bit like the Gardiner type cartridges used early in the war until it was found that they were flimsy and the bullet would separate from the paper sleeve containing the charge. I'll dip the bullet into tallow or a mostly tallow lube.
Lastly, I'll try shooting some like Minie/Burton balls in both my smooth bore and my rifled Model 1842. So, three variables in cartridge construction, and however many variations in powder charges I'll do, say 70-80 grains 2f or 60 grains 3f?
As for N-SSA, only lead round balls can be used in smoothbore skirmish events.
