When I got my first muzzleloader about 1964, a Dixie kit that I put together, an old "Kanoozer", which is what they BP guys called themselves back then, told me that the mountain men cleaned their Hawkens by pouring a couple of quarts of boiling water through the barrels, dried them with "tow", then oiled them with sperm whale oil or bears oil. I still think plain water is the best solvent for BP, but pouring boiling water through the barrel is a real pain! I have never tried rubbing alcohol. It might be OK. I have found that the Shooters' Choice Gel is good. The TC No. 13 stuff has given me after-rust. It does not seem to get all the fouling out, and is particularly bad when used to clean Pyrodex fouling!

Keep yore powder dry!!
