For revolver carriers who count on 357 Magnum self defense ammo, the Remington High Terminal Performance (HTP) line delivers a 158-grain jacketed soft point engineered for controlled expansion and deep penetration. A jacketed soft point is a copper-jacketed lead projectile with an exposed lead tip, designed to initiate expansion on impact while the jacket controls fragmentation—a balance critical for defensive loads where over-penetration and bullet integrity both matter. Remington chambers this load to 1235 fps from a 4-inch test barrel, generating 535 foot-pounds of energy at the muzzle. Waterproof sealant on primers and case mouths prevents moisture ingress during everyday carry, and the brass cases accept standard large pistol primers for straightforward reloading.
Built for the Box
Remington manufactures the HTP series with in-house components: drawn brass cases, Boxer primers, and swaged lead cores under copper jackets. The 158-grain weight mirrors the traditional .357 service load used by law enforcement for decades, offering heavier bullet mass than lighter hollowpoint offerings and deeper tissue penetration in defensive scenarios. The jacketed soft point construction initiates expansion at lower velocities than bonded or monolithic designs, making it suitable for snub-nose revolvers with 2- to 3-inch barrels where velocity drops below advertised figures. Velocity from a 2-inch barrel typically measures around 1100 fps, still sufficient for controlled expansion within 15 yards. Each box holds twenty rounds, packaged in a cardboard tray inside a protective outer sleeve. Remington sources these components domestically and loads them in Lonoke, Arkansas.

This load fits any revolver or lever-action rifle chambered in 357 Magnum. Waterproof sealant extends shelf life in humid environments, vehicles, and pack pockets where condensation collects. The jacketed construction fouls barrels less than cast-lead bullets, and the Boxer primer seats in reloadable brass for shooters who handload match ammunition.
