IMR 3031 is a single base, extruded powder. It exhibits a medium burn speed with many uses, and has long been a favorite of 308 Match shooters using 168-grain match bullets. It is equally effective in small-capacity varmint cartridges from 223 Remington to 22-250 Remington, and it’s a great 30-30 Winchester powder.

Important Information: 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.
