Pyrodex P is intended to be a direct replacement for FFFg blackpowder, when measured volumetrically using a black powder measure. Principal uses for Pyrodex P are in muzzleloading pistols, cap and ball revolvers, and in small bore, muzzleloading rifles.
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.
Select is an enhancement of our RS grade of Pyrodex. Using RS or FFg data in a volumetric measure, Select can significantly reduce group size. Select performs well with sabots and conical bullets. Has also become a favorite among many blackpowder cartridge shooters because of its exceptional consistency. For target use it is the "best of the best".
