IMR 7977 with ENDURON Technology Smokeless Powder 1 Lb
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)

Janet M. Cotton –
I use 7977 in medium bore guns. It works very well in my 7mm Remington Mag and 6.5-06. I get very consistent velocity and it hasn’t been bothered by temperatures that I can tell.
Mallory D. Davis –
Built loads for a 300 PRC with this powder because it was all I could get. Have ran two pounds of it and am getting good accuracy .5moa at 100 Yds. Velocities are consistent and where I would expect them to be.
