IMR® Smokeless Powders

IMR powder has long been a choice powder for knowledgeable reloaders. An acronym for Improved Military Rifle powder, the IMR brand was first introduced by DuPont in the 1930s. Today, IMR is part of the Hodgdon Powder Company family of brands, along with Hodgdon®, Winchester®, and GOEX®. Classic powders like IMR 3031 and IMR 4064 have been popular with reloaders for over 80 years, and continue to be bestsellers today. Originally a line of exclusively rifle powders, IMR has branched out to offer premium handgun, shotshell, and muzzle-loading powder. From varmint hunters to match shooters, IMR reloading supplies continues to offer reliable consistency and power.

Not a brand to rest on its laurels, IMR continues to develop new powder formulas that are increasingly insensitive to weather and temperature changes, have improved burn speeds, and contain additives that remove copper bullet jacket fouling. Leading the pack in terms of innovation is IMR 8208 XBR powder. This accurate metering, super short grain rifle powder is perfect for cartridges like the 223 Remington/5.56mm, 308 Winchester/7.62mm NATO, and the 6mm PPC.

IMR 8208 powder is a great choice for competitors and hunters when accuracy, power, and dependability means the difference between hitting your mark and walking away empty-handed.

Whether you’re reloading for the first time or an experienced reloader who desires elite powder, IMR is a company that should be on your radar. Choose from a variety of powders for everything from small-caliber ammo to magnum rifle cartridges in both 1 lb canisters and 8 lb jugs.
