IMR 7977
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 slowest burn rate of Enduron Technology extruded powder is IMR 7977, and is a true magnum cartridge propellant. It yields outstanding performance in such cartridges as the 300 Winchester Magnum, 7mm Remington Magnum, 338 Lapua, and a host of others. Loading density is perfect for magnums, nicely filling the case at maximum charges, contributing to superb uniformity and accuracy. The 7mm Remington Magnum “never had it so good”!

Do not exceed the loads displayed in the reloaders guide
Never mix any two powders regardless of type, brand, or source
