The hardest part about doing anything with blackpowder is simply getting the powder. The GOEX factory owned by Hodgdon caught on fire last year and they are not going to reopen it. That means not one manufacturer of blackpowder is in America. It all has to be imported from Europe and it is very hard to find right now. I have been trying to get a pound of 4f to prime my flintlock and can't find it. I know I can use 3f but it isn't as good for priming.
Never thought I'd see a problem getting blackpowder but that is the way it is now.
