Hodgdon Pyrodex RS is compatible with all calibers of punched percussion rifles and shotguns. It has the widest range of uses of any pyroex powder. Like other types of pyrotechnics, it produces a cleaner fire and less fouling than black powder. RS is measured against black powder with a 2F particle size.
