Production of IMR powders dates back over 200 years when the company was originally founded by E. I DuPont. Available for use in many reloading applications, the IMR series of powder is trusted by reloaders all across the globe.
The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density, and being environmentally friendly.

Another Enduron Technology extruded powder, IMR 4451, gives top performance in the venerable .30-06, .270 Winchester, and .300 Winchester Short Magnum, to name just a few. This propellant is ideally suited for numerous mid-range burn speed cartridges.
