Winchester Super-X .45-70 Government ammunition delivers the stopping power and accuracy serious shooters demand from big-bore rifle cartridges. Each box of Win Sprx 4570gvt 300gr JHP contains 20 rounds of 300-grain jacketed hollow point ammunition designed for controlled expansion and deep penetration on medium to large game at hunting distances.
The 300-grain projectile exits the muzzle at 1,880 feet per second, generating substantial kinetic energy with manageable recoil characteristics typical of the .45-70 Government platform. This velocity and bullet weight combination produces the terminal performance Winchester Super-X ammunition has been known for since 1922—consistent ignition, reliable feeding, and predictable ballistics that shooters can depend on across modern lever-action rifles and single-shot big-bore platforms.
This ammunition serves hunters pursuing elk, moose, and large-frame game, making it an excellent choice for those who trust Winchester's century-plus track record in ammunition manufacturing. The jacketed hollow point design initiates reliable expansion while maintaining structural integrity through heavy brush and bone, ensuring effective performance in the field.
