The Hodgdon Superformance HSP1 rifle powder delivers velocities 100-200 fps faster than conventional powders while maintaining safe pressures. This spherical propellant maximizes cartridge performance across popular hunting and target calibers without requiring magnum primers or special loading techniques.
What Makes This Different
Superformance technology creates a progressive burn rate that produces higher velocities than standard powders at equivalent pressure levels. The spherical granulation meters consistently through powder measures, reducing charge weight variations that affect accuracy. Independent testing shows velocity increases of 100-200 fps over conventional powders in cartridges from .243 Winchester to .300 Winchester Magnum.Key Features
