I'm selling two 1lb containers of Pyrodex RS muzzleloading powder. $12 for one lb or $20 for both.

Here's Hodgdon's description:
Pyrodex RS is designed for use in all calibers of percussion muzzleloading rifles and shotguns.
It has a wide application of uses and is the most versatile powder in the Pyrodex line. Like all grades of Pyrodex, it burns cleaner and produces less fouling than blackpowder.
RS compares to FFg blackpowder on a particle size basis.
