IMR Enduron 4166 Smokeless Gun Powder


IMR 4166 Enduron is a versatile, match-grade propellant with the Enduron line’s fastest burn rate. It is an extruded powder with a perfect burn speed for cartridges such as the 308 Winchester, 7.62mm NATO, 22-250 Remington, and 257 Roberts, among others.

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 Varget, but the charge weights are significantly different.

Available in 1-LB and 8-LB containers.
