IMR Enduron 4166 is a versatile, match-grade propellant, with the fastest burn rate in the Enduron line. It is an extruded powder with a perfect burn speed for cartridges like 308 Winchester, 7.62mm NATO, 22-250 Remington or 257 Roberts, among other cartridges.

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 Varget but charge weights are materially different.

Great powder for 308 Winchester!

Working up a good hunting load with the 4166 Enduron and the Hornaday 150 gr GMX bullets for my 308. First ladder turned out great! Very happy with the results.
