Hodgdon Triple Seven pellets are formed charges of Triple Seven powder. They are totally sulfur free so there is no bad smell and they leave behind less residue to simplify cleaning. With pellets, there is no need for powder measures or flasks and you won't ever have to worry about messy powder spills again. 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.
