HSM 3571N Cowboy Action 357 Magnum 158gr Semi-Wadcutter Ammo

The HSM 3571N Cowboy Action ammunition delivers consistent accuracy and clean-burning performance for competitive shooters and enthusiasts. This 357 Magnum load features a 158-grain semi-wadcutter bullet specifically engineered for Cowboy Action Shooting competitions and recreational target shooting.

What Makes This Different

HSM's Cowboy Action line uses reduced-velocity loads that minimize felt recoil while maintaining excellent accuracy at typical competition distances. The semi-wadcutter bullet design creates clean, easily scored holes in paper targets, giving competitors a scoring advantage over round-nose alternatives. These loads produce significantly less smoke and fouling compared to traditional black powder substitute loads, keeping firearms cleaner during extended shooting sessions.

Key Features

• 158-grain semi-wadcutter bullet for precise target scoring
• Reduced-velocity load minimizes recoil and muzzle blast
• Clean-burning powder reduces fouling buildup
• Brass cases suitable for reloading applications
• Consistent velocities for predictable point of impact
• Lead bullet construction meets most competition requirements
• Bulk packaging with 500 rounds per case (10 boxes of 50)

This ammunition performs reliably in both single-action revolvers and lever-action rifles chambered in 357 Magnum. The moderate velocity makes it ideal for steel target competitions where ricochets must be minimized, while the semi-wadcutter profile ensures clean cuts through cardboard and paper targets. Temperature stability maintains consistent performance across varying weather conditions during outdoor matches.
