Description

IMR Enduron 4955 is a versatile match-grade extruded rifle powder engineered for precision, consistency, and high-performance big game hunting applications. Positioned between IMR 4451 and IMR 7977 in burn rate, Enduron 4955 offers an ideal balance of velocity, loading density, and temperature stability for a wide range of rifle cartridges.

Designed for cartridges such as .25-06 Remington, .270 Winchester, .280 Remington, and .300 Winchester Magnum, IMR 4955 delivers consistent ignition, reliable velocities, and excellent shot-to-shot uniformity. Its optimized burn characteristics make it well suited for hunting and long-range precision shooting with medium- to heavy-weight bullets.

As part of the Enduron series, IMR 4955 incorporates advanced copper fouling reduction technology and additives engineered to minimize sensitivity to temperature changes. This helps maintain stable pressures and consistent ballistic performance in both hot and cold conditions while reducing barrel fouling over extended shooting sessions.

Comparable in performance range to Hodgdon H4831, IMR Enduron 4955 provides reloaders with a modern, environmentally conscious propellant designed for dependable magnum and standard rifle performance.
