IMR 8133


The latest IMR Legendary Powder, IMR 8133, is an Enduron Technology

powder. It was designed to provide optimum performance in the large overbored cartridges

like the 300 Remington Ultra Magnum, 6.5mm-300 Weatherby Magnum, 28 Nosler and a

host of other fine magnum cartridges. It provides excellent loading density, copper fouling

eliminator, insensitivity to extreme temperature changes and is environmentally friendly. It is,

without equal, the consummate big game cartridge propellant.
