The HSM 38401N Cowboy Action ammunition delivers authentic period-correct performance for 38-40 Winchester firearms with carefully loaded 180-grain round nose flat point bullets. This traditional loading replicates the ballistics and feel of original frontier cartridges while meeting modern safety standards for competitive shooting and historical firearms.
What Makes This Different
HSM's Cowboy Action line uses reduced-velocity loadings specifically engineered for vintage firearms and competitive shooting sports. Unlike standard high-pressure loads that can damage older actions, these cartridges generate approximately 25% less chamber pressure while maintaining reliable cycling. The 180-grain bullet weight matches historical specifications used in the American West, providing authentic recoil characteristics and downrange performance.
Key Features
- 180-grain round nose flat point bullets for authentic period performance
- Reduced-pressure loading safe for vintage and replica firearms
- Clean-burning powder minimizes fouling in competition environments
- Consistent velocities averaging 750-800 fps from 20-inch barrels
- Boxer-primed brass cases suitable for reloading applications
- 50-round boxes with 10 boxes per case (500 total rounds)
- SAAMI-specification dimensions ensure reliable feeding and extraction
This ammunition excels in Cowboy Action Shooting competitions where period-correct ballistics and reliable function take priority over maximum velocity. The round nose flat point design provides clean target holes for accurate scoring while the moderate velocity reduces felt recoil during rapid-fire stages. Range testing shows consistent groupings under 3 inches at 50 yards from quality revolvers and lever-action rifles.
