Description
IMR Enduron 7977 is a slower burn rate in the Enduron family. Loading density is perfect for magnums, contributing to superb uniformity. This is a true magnum propellant yielding outstanding performance in 300 Winchester Magnum, 7mm Remington Magnum and 338 Lapua, among other cartridges. Loading density is perfect for magnums, nicely filling the case at maximum charges, contributing to superb uniformity and accuracy.
The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly.
IMR 7977 performs comparably to Hodgdon H1000 but charge weights are materially different.
Made in Canada.
Available in 1-LB and 8-LB containers.
