This is a dense, spherical powder originally designed for the .50 BMG military cartridge. Due to its unique characteristics, it has also become a highly effective propellant for a wide range of large-capacity, overbore magnum rifle cartridges. It's known for its ability to produce maximum velocities with heavy bullets in calibers like the 7mm Remington Ultra Magnum, .300 Remington Ultra Magnum, and .30-378 Weatherby Magnum. Its consistent performance makes it a popular choice for long-range match shooting, including applications at 1,000 yards.
