IMR 7977 with ENDURON Technology Smokeless Power 8 Lbs
by HODGDON , IMR & WINCHESTER
The slowest burn rate 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”! Grain shape is extruded (stick)
