Hodgdon Superformance Spherical Rifle Powder is manufactured by a company with more than 60 years in the business of reloading. This spherical powder is made to deliver powerful velocities in various cartridges, including the .300 Winchester Short Magnum, .22-250 Remington, and .243 Winchester. Based on the design of this powder, velocities can reach well beyond 100 feet per second greater than the best hand loads published and larger gains compared to ammunition coming directly loaded from the factory. This propellant is made for very specific applications, and while the number of cartridges is limited, the powder is still an exceptional buy.
