I've hiked my muzzy (Knight Bighorn) in to some beautiful roadless places!  My kit includes patches for cleaning, a "quickdraw" filled with a lot of extra musket caps (noise dampened by spare patches), 5 quickdraws filled with powder, 5-6 extra bullets and sabots, a small vial of solvent, a breech plug wrench (yes, heavy).  I keep all this in a plastic Ziploc bag in my "hip bag".  I bring a small roll of electrician's black tape to seal the muzzle if things get rainy.  
Not very traditional, all of this, but it works.  Good luck on your hunt!
