This new Enduron extruded powder is a top PERFORMER with such great

cartridges as the 270 Winchester, 25-06 Remington, 280 Remington and 300 Winchester

Magnum, and many, many more. It falls directly between IMR 4451 and IMR 7977 in burn

speed, providing top performance for all cartridges used for big game. As with all Enduron

powders, it is temperature insensitive, clean burning, minimizes coper fouling and is totally

safe for the environment.
