Description

IMR Enduron 4166 is a versatile match-grade extruded rifle powder engineered for precision, temperature stability, and reduced copper fouling. As the fastest-burning powder in the Enduron series, 4166 is optimized for a wide range of popular rifle cartridges used in precision shooting, hunting, and competition applications.

Its balanced burn rate makes it an excellent choice for cartridges such as .308 Winchester, 7.62 NATO, .22-250 Remington, and .257 Roberts. IMR 4166 delivers consistent ignition, reliable velocities, and excellent loading density, helping reloaders achieve repeatable accuracy and dependable ballistic performance.

The advanced Enduron formula includes a built-in copper fouling eliminator along with additives designed to reduce sensitivity to temperature changes. This helps maintain consistent pressures and velocities across varying environmental conditions while minimizing barrel fouling during extended shooting sessions.
