The original powder charge for a land pattern musket was 6-8 drams ( 27.3 grains ) of gunpowder. Bear in mind it was not as chemically efficient as today's powders. The issue ball was a .690-.695 diameter. Original barrels had to accept a .765 pin and refuse a.785 pin making the nominal caliber .775, that is why most component packages from Track and the Rifle Shop have .775 bores. While we are on the subject, I have many copies of French and Indian War journals, orders and quartermaster issues and the gun is referred to as musket, land pattern musket with either single or a double bridle lock and almost always with a wooden ramrod. The term Bess does not appear once. For hunting, I use a .695 ball with a paper cartridge of 75 grains of FFG and prime with the same. So about 70 grains goes down the barrel. The gun can be made to shoot better with a .715 or a .735 ball with wadding or a patch but that is not what they used back in the day. I carry a horn, loose ball and un-rolled paper cartridges for wadding. Many journals state the Ranger and Provincial troops disassembled their paper cartridges and put the powder in a horn, loose ball in a shot pouch or shot bag and carried the papers as wadding. No mention of priming horns is ever stated. My accuracy is good at smooth bore ranges, I opt for shot placement over power. Photos show my equipment and targets at 25 and 50 yards
