IMR

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. In 2003, Hodgdon Powder Company acquired the IMR brand bringing these prestigious powders under the umbrella that also includes Hodgdon, Winchester, Accurate, Ramshot, and more.  Any gunpowder required by handloaders can be sourced through these brands.
