For me, when I actually ML hunt anymore, it's the 1/4 pound capacity horn buckled to the straps of my shooting bag (in lieu of the 3/4 pound horn used at "rifle frolics"), a handful of balls and pre-cut pre-lubed patches, and a couple spare flints (or a Ted Cash capper as the case may be- the one I've been using for nigh on 40 years now) and the brass powder measure. The bag is a double bag with compartments for each necessity, and after decades of use and many shots loaded from it, my hand dives unerringly into it for what I need- a reload is accomplished very fast. I could do it blindfolded.
The only time I resorted to pre-measured loads was when I carried an 1861 Springfield (original) or a repro .577 Enfield (Parker-Hale)- in which case it was a minie ball and 60 grains FFFg in a historically accurate paper cartridge.
