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.
IMR 800-X large-grained flake powder is at its best when used in heavy field loads from 10 gauge to 28 gauge. In handgun cartridges 800-X performs superbly in cartridges like the 10mm auto and 44 Remington Magnum. Excellent velocity and uniformity translate into top accuracy.
