There is no better instruction in this endeavour than the original step by step as provided by the French Government.
My own method differs slightly, in that I use a tapered mandrel for the shape, adjusted by the charge needed and diameter of the ball.
The reason for the taper, is that when in the pocket, they sit ball down and are easily and quickly retrieved. Due to the shape and sealed point,
the ball is placed into the ctg last. I've found with the tapered end, less powder is lost and insertion into the muzzle is easier and faster.
Now, the French Way:
An English Ctg., similar except for the string tie below the ball + a tied end.
American, buck and ball:
My tapered ctgs. with the tapered form along with a box for carrying more than a few in the pocket.
These particular ctgs. have a .715" ball and 90 or so gr. of 3F.
Incidentally, these paper ctg. appear to work well down to .54 calibre as bound by forum member Bruce S.
Dan Pharris also found they worked well in his .16 bore rifle and as Bruce and I found, shoot to the same point
of impact and with the same accuracy as patched round balls, in our rifles. Bruce used a .72 cal. rifle.
