HSM Cowboy Action 45-70 Govt ammunition brings authentic, historically appropriate loads to your lever-action rifles and single-shots. Whether you're competing in formal Cowboy Action Shooting matches or simply enjoying a weekend with the classic rifles that define American hunting heritage, HSM's 405-grain hard cast flat nose rounds deliver consistent, reliable performance downrange. Built for shooters who respect the cartridge and the tradition it represents, these loads pair modern quality control with the straightforward, no-nonsense approach that defines working ammunition.

The 405-grain hard cast bullet is the weight and profile that Cowboy Action Shooting rules and period-correct firearms demand. Hard cast construction resists deformation and provides the clean, predictable ballistics you need for both competitive stages and hunting applications where this venerable cartridge still earns its keep. The triple lug groove design aids in bullet stability and cast integrity—details that matter when you're running the same rifle your great-grandfather might have.

HSM has built a reputation on delivering solid, affordable ammunition across an extensive range of calibers, and their Cowboy Action line upholds that standard. Each round is loaded with the same attention to consistency you'd expect from serious ammo manufacturers, but without the premium pricing. This is working ammunition for working shooters—whether that work is competition, hunting, or simply the satisfaction of shooting authentic loads through authentic rifles.
