Add Muzzle loader to the list of SHTF guns?

You can't make caps so it had better be a flint lock....or I don't know how.
Black powder isn't that easy to make from scratch either. I used to do it as a kid but I bought the sulfur and potasium nitrate. The charcoal is easy. You need s source for the sulfur and refining the potasium nitrate from bat dung or **** or whatever is not that easy.
If you need to stock caps I'd just stock ammo.
To me black powder doesn't make mush sense. I think I'd rather have a long bow.
