At black powder velocities, almost anything will work, including hog lard. My BP lube is hog lard and beeswax. Junior uses
a little alox, but I don't see the benefit. I mix a 3:1 ratio or maybe a little less beeswax, depending on how hard I want the lube to be.
Like I said, though, at BP velocities anything will work. If you simply want to tumble them in Alox, that'll work too. Which reminds me, I need to order some Xlox.
