Hodgdon Pyrodex Select is an enhancement of our RS grade of Pyrodex. Using RS or 2F data in a volumetric measure, Select can significantly reduce group size. Wonderful news to the deer hunter is that Select performs well with sabots and conical bullets. Select 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". Note:Do not exceed the loads displayed in the reloaders guide. Never mix any two powders regardless of type, brand, or source. Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
