357 Magnum HSM Cowboy Action 825 fps 158 Grain SWC 50 Rounds

The HSM Cowboy Action .357 Magnum delivers authentic, competition-ready performance tailored for cowboy action shooting, single-action revolvers, and traditional lever-action rifles. This load features a 158-grain semi-wadcutter (SWC) lead bullet with a flat-nose, full-diameter design optimized for clean, round holes in paper targets, excellent ballistic consistency, and superior accuracy at cowboy action distances.

From a standard test barrel, this ammunition achieves a muzzle velocity of 800–850 fps (typically ~825 fps), producing 225–250 ft-lbs of muzzle energy for very light recoil, flat trajectories, and manageable follow-up shots — perfect for fast, precise shooting in timed stages. The soft lead semi-wadcutter profile minimizes barrel leading when used in properly maintained firearms and provides reliable feeding in both revolvers and lever guns.

Brass-cased with non-corrosive Boxer primers and clean-burning, low-flash propellant, these rounds ensure consistent ignition, smooth cycling, and excellent shot-to-shot uniformity. 50 rounds per box.
