Doug Pratt mentions an apparent shortage of Pyrodex pellets. Pyrodex is a black powder substitute used by muzzle-loader enthusiests that isn't regulated nearly as strongly as the regular stuff. We use the pellets to pre-heat the fuel grain in our hybrid rocket motors. I need some, but haven't been looking too hard (WalMart hasn't had them though, which is unusual around hunting season). Good thing we can get them through Amazon. Gotta love it.
