My muzzleloader of choice is an old Thompson-Center Big-Boar 58-cal using traditional #11 caps for ignition. I am contemplating ordering some real black powder (Graf and Sons has Schuetzen 2F in stock) but most places have a fairly larger minimum (ie Grafs and Sons wants you to order at least four pounds and there is a huge hazmat fee). I could order some smokeless too pad that out but at the moment I am not in need of any smokeless. No where local carries black powder but most of the common substitutes are available. If you were going to step away from the real thing in a tradition percussion gun what substitute would you go to?
