Description

IMR Enduron 8133 is the slowest-burning powder in the advanced Enduron series, engineered specifically for high-capacity magnum rifle cartridges and extreme long-range performance. Designed to provide exceptional loading density and uniform ignition, 8133 delivers consistent velocities and outstanding accuracy in demanding shooting applications.

Its slow burn rate makes it ideal for large overbore magnums such as 6.5-300 Weatherby Magnum, .264 Winchester Magnum, 28 Nosler, and .300 Remington Ultra Magnum. Near-full case fill at maximum charges promotes highly uniform pressure curves and repeatable ballistic performance, especially with heavy-for-caliber projectiles.

Like all powders in the Enduron family, IMR 8133 incorporates advanced copper fouling reduction technology, temperature stability, and environmentally conscious additives. These features help maintain accuracy during extended shooting sessions while reducing barrel fouling and preserving consistent performance across varying climates.

Comparable in application range to Hodgdon Retumbo, IMR Enduron 8133 is an outstanding choice for precision magnum reloaders seeking maximum consistency and long-range capability.
