And, a company called Jacks Powder Keg sells a GOEX produced powder that is labelled "Jack's Battle Powder." It's the same granule size as 3F, but doesn't have the graphite glazing. Originally marketed to re-enactors, Muzzleloader magazine ran an article on the stuff about a year or two ago on it's use as a propellant in rifles and tradeguns, and didn't find anything really wrong with it. (The hint was that it might even clean up easier without the glazing.)
Powderinc still lists KIK and Diamondback powders for sale, too. Diamondback is made in a re-worked plant south of the border somewhere, maybe Brazil, if memory serves.
