I've used the mixture Prairie Dawg mentioned. I drained the liquid into small canning containers when it was still warm. The seal on the containers actually depressed to my surprise. Still have some packed away that I made up about two years ago. I just warm up a chunk of it and then soak it up in a felt pad. Punch whatever caliber I need out of the felt pad for cartridges. There's some waste but I have plenty. I forget what I read at the time, but I bought some 100% wool felt to make the patches. I've not shot a lot compared to the black powder shooters here. Worked pretty well for me though.
If you'd like to try some out send me a PM. I have more than I need. It was a fun project though.
