The HSM Cowboy Action Rifle Ammunition 45-70 Govt 405gr RNFP brings the look and ballistics shooters expect from a dedicated Cowboy Action series, offering a 405 grain round nose flat point bullet that delivers about 1300 fps muzzle velocity and roughly 1520 ft-lbs of energy for authentic ballistic performance in vintage-style rifles and modern reproductions. Chambered in .45-70 Government with brass cases and made in the United States, this load works well for cowboy action matches, range practice with big bore lever guns, and historical shooting demonstrations where period-appropriate ballistics and reliable feeding are important. If you run cowboy silhouette, single-action pistol/caliber conversions, or spend weekends drilling iron sights on buffalo-style targets, the RNFP profile provides consistent wound channels and smooth chambering in tubular and box magazines alike. The HSM Cowboy Action series is aimed at shooters wanting accessible, dependable rifle ammunition that balances traditional handling with contemporary safety markings and transport considerations; casual hunters and target shooters will find the trajectory, energy, and manageable recoil a good match for large-game practice and long-range target work with classic firearms.
