The 45-70 Government is one of America's most storied rifle cartridges, and HSM's 300-grain Sierra HP/FP load brings modern precision to this classic round. Built with a flat-nose design, this ammunition feeds reliably through lever-action rifles and single-shots alike while delivering consistent ballistics shot to shot. Whether you're hunting big game or shooting a vintage Marlin or Winchester, this round pairs HSM's reputation for tight tolerances with Sierra's proven bullet construction.

The 300-grain Sierra hollow point flat-nose bullet is engineered for controlled expansion and deep penetration on medium to large game. Its heavy-duty jacket and lead core work together to manage energy transfer and ensure the round does what you ask of it downrange.

This is ammunition built by people who understand that reloading precision matters when lives and harvests are on the line.

Each box contains 20 rounds, and we stock it in cases of 25 boxes—a practical format for serious shooters and hunters who shoot their 45-70 regularly. If you run a lever-gun or single-shot rifle in this caliber and want ammunition that respects the cartridge's heritage while backing it with modern quality control, HSM's Sierra load is a no-nonsense choice.
