The HSM Cowboy 38-55 Winchester 240-grain round nose flat point ammunition delivers reliable, historically-accurate rifle cartridges purpose-built for lever-action and single-shot rifle enthusiasts, cowboy action competitors, and collectors of classic American firearms. This 20-round box format makes it ideal for range training, competition use, and field applications where the venerable 38-55 Winchester caliber remains a respected choice for medium-range accuracy and modest recoil impulse.
HSM manufactures this cartridge with consistent loading standards that ensure uniform velocity and pressure profiles across each round. The 240-grain round nose flat point projectile profile is specifically designed for controlled expansion and deep penetration in hunting scenarios while maintaining dimensional stability through lever-action magazine feeds and single-shot chambers. HSM's quality control and brass-cased, boxer-primed construction support reloading, extending value for shooters who process their own ammunition—a common practice among traditional rifle users.
Shooters with Winchester Model 1895, Marlin 1895, and other classic lever-actions chambered in 38-55 Winchester will find this ammunition immediately compatible without modification or feeding concerns. The 20-round box format is standard for this cartridge; cases ship in master cartons of 25 boxes, making bulk purchasing economical for club ranges, instructional programs, or serious competitors running multiple matches. Whether you're preserving historic rifle capability or seeking sub-MOA accuracy at medium distances, HSM Cowboy ammunition delivers the ballistic consistency required.
