The swedish military match lock musket M/1620 had a regulated charge of 19,9 grams of black powder!
Yes, 19,9 grams, and that is a tremendous charge, even though apr. 0,5 grams was used for priming.
When proof firing one of the first match lock muskets that I built I brought 8 balls of apr 38,0 grams and 8 premeasured charges of 8,0 grams of Fg black to the range. After 5 rounds I had to quit because of the heavy recoil. That was of course partly due to the shape of the butt end of that spanish-dutch type of musket that was common in Europe, including Sweden, in those days. And which is the type of musket that I generally build.
Later, on March 20 1683 ,the proofing load for a swedish match lock musket, was regulated to be 40,0 grams, and the ball should be apr. 48 grams.
You have to take into consideration,though, that BP of those days, 16th and 17th centuries, most certaily was of inferior quality and strength compared to modern black. On the other hand, I undertook careful tests many years ago on a batch of 18th century black powder, that had been stored in that museum for at least two hundred years. And that black showed no signs of weakness. On the contrary, when cronographed it was even superior to modern BP, and when fired with upon 3 mm sheet steel, it showed a tremendous inpact, fully comparable to modern swedish and german black, that was also tested in the musket.
It is considered that the swedish king Gustavus Adolphus introduced the paper cartridge ,including powder and ball ,during the thirty years war, and to be carried in a cartrridge box by the soldier.
