US869 is a true magnum Spherical rifle powder that is superb with heavy bullets in big, overbore rifle cartridges. US869 is a dense propellant that allows the shooter to use enough powder to create maximum velocities in cartridges such as the 7mm Remington Ultra Magnum, 300 Remington Ultra Magnum, 30-378 Weatherby Magnum and others. US869 is superior in the 50 Caliber BMG where it yields high velocity and great accuracy with 750 to 800 grain projectiles. This is a fine 1000-yard match propellant! In addition, US869 is effected minimally by varying temperatures, a key feature for top competition and hunting accuracy.
