Pig jam. I only fired it once but seen it jam up many times.There is another.... ME, never have never will.
After loading and clearing jams with an M-60, flintlocks are nothing.
Load your flinter by the numbers. Do it all day until you have made muscle memory.
I have not fired an M-60 since the 80s, but still can. Muscle memory exorcises.
Same with long sword, hawk and knife. They are all on the same principle.
