IMR Enduron 4451 Smokeless Gun Powder


In the Enduron line, IMR 4451 is a versatile, match-grade propellant with a mid-range burn speed. It is an extruded powder that is ideal for cartridges such as the 270 Winchester, 30-06, and 300 Winchester Short Magnum.

The Enduron series is distinguished by its copper fouling eliminator, insensitivity to temperature changes, ideal loading density, and environmental friendliness.

The performance of this propellant is comparable to that of Hodgdon H4350, but the charge weights are significantly different.

Available in 1-LB and 8-LB containers.
