Insofar as my research has discovered, the sole US manufacturer of small arms smokeless powder remaining today is St. Marks in Florida. They make only ball powders. I have seen no definitive information, but the belief is that St. Marks at present is making powder only for military related purchasers, none for civilian reloader outlets such as Hodgdon. All other sources of powder are foreign imports from Canada, Australia, Germany, Sweden, Switzerland, Finland, and several other nations. Some talk about White River getting into powder manufacture, but that is just talk.
