HSM 38551N Cowboy Action 38-55 Win 240gr RNFP Ammo 20 Rounds

The HSM 38551N Cowboy Action ammunition delivers authentic black powder ballistics in modern brass cases for competitive shooters and historical firearm enthusiasts. This 38-55 Winchester load features a 240-grain round nose flat point bullet specifically engineered to meet SASS velocity requirements while maintaining consistent accuracy across vintage and reproduction rifles.

What Makes This Different

Unlike standard hunting loads that push velocities beyond historical norms, HSM's Cowboy Action series replicates original black powder performance with clean-burning smokeless powder. The reduced velocity minimizes recoil and barrel wear while providing the flat-nosed profile required for tubular magazine safety. Each cartridge delivers velocities between 1,200-1,300 fps, matching period-correct ballistics that competitive shooters demand.

Key Features

• 240-grain round nose flat point bullet for tubular magazine compatibility
• Reduced velocity loads replicate black powder era performance
• Clean-burning powder minimizes fouling and smoke production
• SASS-compliant velocities for competitive cowboy action shooting
• Quality brass cases suitable for reloading applications
• Consistent powder charges ensure shot-to-shot reliability
• 20 rounds per box with 25 boxes per case configuration

This ammunition excels in single-shot rifles, lever-action carbines, and reproduction firearms chambered in 38-55 Winchester. The moderate velocities reduce felt recoil significantly compared to modern hunting loads, enabling faster follow-up shots during timed competition stages. The flat point design prevents chain-fire incidents in tubular magazines while delivering adequate terminal performance for metallic silhouette targets and cowboy action scenarios.
