Superformance delivers striking velocities in cartridges like the 22-250 Remington, 243 Winchester and 300 Winchester Short Magnum. Targeted velocities are well in excess of 100 fps over the best published handloads and even larger gains over factory ammunition!
Because this propellant is tailored for specific applications, the number of cartridges and bullets is limited, but where it works, it really works!
