The HSM Cowboy 38-40 Winchester 180gr RNFP ammunition is purpose-built for shooters who demand reliable, historically accurate cartridge performance in legacy firearms and modern reproductions alike. Chambered in the 38-40 Winchester—a classic rifle and handgun cartridge with deep roots in Old West history and cowboy action shooting—this round serves hunters, sport shooters, and firearms enthusiasts who operate Winchester 1892 rifles, Colt Peacemakers, and similar period-correct or replica platforms. HSM's Cowboy line is engineered specifically for these applications, delivering consistent velocity and accuracy without the performance overkill of modern defensive or hunting loads.
Each round features a 180-grain round-nose flat-point (RNFP) projectile—a geometry chosen for its reliable feeding in lever-action magazines and revolvers, and its terminal performance in the subsonic velocity range typical of 38-40 Winchester loads. The RNFP design minimizes feed-related malfunctions while delivering controlled expansion at traditional rifle velocities, making it ideal for medium-game hunting and target work at typical shooting distances. Loaded to factory specifications for accuracy and safety across firearms of varying age and condition, this ammunition meets the expectations of competitors in Cowboy Action Shooting (SASS) events and recreational shooters who value authenticity and dependability over maximum velocity.
This product is sold as 50 rounds per box, with 10 boxes per case for a total of 500 rounds—a practical quantity for serious practitioners of classic rifle disciplines or those stocking for regular range sessions with vintage firearms. Cowboy Action competitors, Winchester 1892 owners, and single-action revolver enthusiasts will appreciate HSM's consistent quality and historical accuracy. The compact 3.2 x 1.95 x 6.2-inch case dimension and 2.1-pound weight per 50-round box make this ammunition convenient for storage, transport, and field use.
