This outstanding spherical propellant offers significant advantages in many magnum rifle applications. Optimized for high velocity in 50 BMG, US 869 delivers great accuracy with 750 to 800 grain projectiles. It's also excellent for heavy bullets in big, overbore rifle cartridges so you can create maximum velocities in cartridges like the 7mm Rem Ultra Mag, 300 Rem Ultra Mag, 30-378 Weatherby Mag, and others. Minimally affected by temperature for consistent performance.
