IMR Enduron 4451 Smokeless Gun Powder

IMR powder production dates back more than 200 years, when E.I. DuPont founded the company. The IMR series of powder is trusted by reloaders all over the world and is suitable for a wide range of reloading applications.

The Enduron series is distinguished by its copper fouling eliminator, insensitivity to temperature changes, ideal loading density, and environmental friendliness. Fill your tag during a heat wave, and sight in your rifle when it’s subzero. IMR 4451, another Enduron Technology extruded powder, performs admirably in the venerable.30-06,.270 Winchester, and.300 Winchester Short Magnum calibers, to name a few. This propellant is ideal for a variety of mid-range burn speed cartridges.
