+1 about Track of the Wolf. Another source is Dixie Gun Works but I'd look at TotW first.

The most convenient way to buy real black is online from an outfit like Powder Inc. The trick, if there is one, is to order it in bulks shipments. Powder Inc charges $17.90/lb for a 10 pound shipment....that price includes the HazMat charge. Granulations can be mixed. Still, it is a $180 bill going out the door. Should last awhile, though.
