I personally use both, I have all my spare stuff, powder, flints, caps, etc., and tools in a range box I built, and then I have my supplies for what I am shooting at the moment in a pouch, also home made. Using the pouch helps to keep me in practice at retrieving patch and ball when not at the range but out in the wilds. I have a nice sized horn for my main load and a neat little horn I put together for priming when using one of my flintlocks. I just like to keep things the same no matter where I am shooting.
