Federal Premium HST 357 Magnum 154gr JHP Ammo - 20 Rounds

The Federal Premium Personal Defense HST 357 Magnum delivers consistent expansion and deep penetration through barriers commonly encountered in defensive situations. This 154-grain jacketed hollow point ammunition represents Federal's flagship defensive load, engineered for maximum stopping power in revolvers and lever-action rifles.

What Makes This Different

The HST (Hydra-Shok Two) projectile features a mechanical jacket-to-core bond that prevents separation during expansion. Unlike standard hollow points that can clog with clothing or drywall, the HST's engineered cavity maintains expansion through FBI protocol barriers. Independent testing shows 99% weight retention and expansion ratios exceeding 1.5x original diameter.

Key Features

• 154-grain jacketed hollow point with bonded core construction
• Nickel-plated brass cases resist corrosion and aid extraction
• Low-flash propellant reduces muzzle signature in low-light conditions
• Consistent 1,240 fps muzzle velocity from 4-inch barrels
• Optimized for revolvers with 3-inch to 6-inch barrel lengths
• FBI protocol tested through heavy clothing, wallboard, and automotive glass
• Premium boxer primers ensure reliable ignition in all conditions

This load performs consistently across temperature extremes from -20°F to 140°F without velocity degradation. Law enforcement agencies nationwide rely on HST technology for duty use, while civilian shooters choose it for home defense and concealed carry applications. The 154-grain weight provides optimal balance between expansion and penetration in the .357 Magnum platform.
