The civil was group I used to be in did 12-15 school presentations a year. My little 20 minuet speal was on Civil War Soldiering and firearms. Springfield rifled musket, colt army and navy, G&G, Remington new army.....and on occasion the Philadelphia derringer.
Hats off to you sir for doing a presentation on such an important subject
.
Another common round-ball "cartridge" (or charger rather since it wouldnt truly be a combustible cartridge) would be basically what you have there, but with the ball enclosed inside the paper tube; and a cotton thread tied above and below the lead ball. Nip off the pigtail end (normally with thine teeth
) dump in the powder, then rip the ball from the paper and seat it as normal. This cartridge and loading process is clearly depicted in the back of "An Introduction TO Civil War Small Arms" by E.J. Coats and D.S. Thomas.
(we always used coarse grained salt in light of powder just for the Schools red tape sake)
