Win Sprx 4570gvt 300gr Jhp 20/200

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 engineered for controlled expansion and deep penetration on medium to large game at hunting distances and tactical training scenarios.

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. The jacketed hollow point design initiates reliable expansion while maintaining structural integrity through heavy brush and bone.

This ammunition serves hunters pursuing elk, moose, and large-frame game, as well as shooters conducting precision rifle training with classic .45-70 Government rifles. The 20-round-per-box configuration supports range sessions, field hunting applications, and stockpiling by serious enthusiasts who trust Winchester's century-plus track record in ammunition manufacturing. Whether you're conditioning a newly acquired Sharps, Marlin, or custom single-shot, Winchester Super-X .45-70 Government provides the consistency and terminal performance expected from a flagship hunting cartridge.
