HSM Ammunition Bear Load .357 Magnum 180 Grain Hard-Cast RNFP Gas Check ammunition is engineered for deep, straight-line penetration in demanding backcountry conditions. The heavy-for-caliber 180-grain hard-cast Firearm Ammunition bullet, rated at 15 BHN, resists deformation against thick hide and heavy bone, helping ensure maximum penetration on large predators. The Firearm Ammunition design creates an effective wound channel without relying on expansion, while the gas-checked base reduces barrel fouling and maintains accuracy at higher velocities. Delivering 1,200 fps and 576 ft-lbs of energy, this load is well suited for wilderness defense and hunting applications requiring hard-hitting performance. Packaged 50 rounds per box in reloadable brass cases.
