I think you will find that the 44's will work with 25 to 30 gr. FFFG, and the 36's with 18 to 25 gr. The chamber length will dictate the exact amount. The paper cylinder is close to the same length, just differs in diameter, and the charge is quite forgiving, as the tail or excess is folded over. Simply adjust the amount of powder to arrive at the correct length for your chamber.
There are also two methods of attaching the ball,or bullet whichever is desired, either fold the paper over the entire projectile and glue the fold, or glue to the projectile, leaving a portion of the lead exposed. If you use nitrated paper, you can use a slightly heavier paper, as it will not need to burst when rammed home in the chamber.
Some of the old Lyman loading manuals and cast bullet manuals gave directions for making them.
