US 869 is a 50 BMG propellant that offers significant advantages in many magnum rifle applications! A true magnum spherical rifle powder, it 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. It offers a superior solution for 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!
