Hodgdon Powder offers the largest selection of quality smokeless propellants for any reloading application. Hodgdon US 869 leads the way again by developing an outstanding 50 BMG propellant that offers significant advantages in many magnum rifle applications! 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 affected minimally by varying temperatures, a key feature for top competition and hunting accuracy.
