The Remington High Terminal Performance (HTP) 357 Magnum load chambers a 158-grain semi-jacketed hollow point — a defensive cartridge designed for revolvers where expansion and retained weight matter. 357 Magnum ammunition occupies a niche between everyday range fodder and premium bonded loads, offering reliable terminal performance at a moderate price point. You’ll run this load in medium- and large-frame revolvers chambered in 357 Magnum, or as a full-power option in lever-action carbines that accept the round.
Performance at a Glance
Remington loads the HTP line with a priority on expansion mechanics. The 158-grain SJHP leaves a 4-inch test barrel at 1235 fps, producing 535 ft-lbs of muzzle energy. The semi-jacket design — lead core with a thin copper cup that stops short of the nose — allows the hollow-point cavity to initiate expansion on impact while the jacket controls peel-back and holds the core together. Remington sources first-quality brass cases and Kleanbore primers for this load, maintaining consistent ignition and enabling reuse of the brass after firing.

This load fits any revolver or carbine chambered in 357 Magnum ammo. Velocity will vary with barrel length — shorter snub-nose barrels will see lower fps, while carbines may exceed the published figure. The 158-grain weight sits at the heavier end of common 357 Magnum loadings, offering deeper penetration than lighter 125-grain options at the cost of slightly more felt recoil.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Treat every firearm as if it is loaded. Keep the muzzle pointed in a safe direction at all times. Keep your finger off the trigger until ready to fire. Be certain of your target and what lies beyond it.
- Verify current state and local laws before purchasing or possessing ammunition — some jurisdictions restrict hollow-point projectiles or impose additional background-check requirements.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and reproductive harm. Wash hands thoroughly after handling fired cases or cleaning firearms. Ventilate indoor ranges and wear eye and hearing protection.
