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 IMR brand was first introduced under DuPont in the 1930’s. IMR is an acronym for Improved Military Rifle. The first IMR reloading powders included ever popular favorites IMR3031 (1934), IMR4064 (1935) and IMR4350 (1940). Each of these are still favorites with handloaders today! The IMR series of handloading powders were the only choice to wring full performance out of rifle calibers. For this reason, the IMR brand powders truly are Legendary products.
The IMR brand was created under the DuPont Corporation. In fact, E. I. duPont arrived in America in 1800 determined to make an improved gunpowder and, by 1802, was producing gunpowder in a new plant along the Brandywine River in Wilmington, Delaware (this plant morphed into what is today the GOEX brand of black powder).
