A priming horn or brass tube pan primer and a flint knapper to keep your flint sharp the little tube pan primers have a ball on the end that does a nice job of knapping an edge on your flint.
Don't fill the priming pan all the way, you want it to flash into the main charge not burn it's way in, once you have that figured out it will be nearly as fast as a percussion rifle.
I can't highight this enough 1/4 of a pan is plenty and tip your rifle a bit to get some pan powder into the flashole. doing this significantly increased my locktime on my deerstalker
