IMR Enduron 4451 is a versatile, match-grade propellant with a mid-range burn speed in the Enduron line. It is an extruded powder and is perfect for cartridges like 270 Winchester, 30-06 or 300 Winchester Short Magnum, among others. The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly. This propellant performs comparably to Hodgdon H4350 but charge weights are materially different.
