You're right! Back in the day it was powder, ball, and a cap. I use a lubed wad to lube the barrel as you fire. It keeps the black powder fouling soft. You can also do this buy putting some kind grease over the ball. But thats makes a huge mess. I do it sometimes on the first cylinder, because other wise that first ball is going down the barrel dry.
