For defensive shooters who demand consistent expansion and deep penetration, Remington High Terminal Performance (HTP) 40 S&W ammo in 155-grain jacketed hollow point (JHP) delivers field-proven terminal ballistics. This 40 S&W self-defense ammo pushes a 155-grain JHP bullet to 1205 feet per second from a 4-inch test barrel, generating 500 foot-pounds of muzzle energy — velocities engineered to balance controlled expansion with barrier penetration in real-world defensive encounters.
Load Profile
Remington loads the HTP line with waterproof sealant applied to primer pockets and case mouths, a critical detail for carry ammunition exposed to humidity, perspiration, and temperature swings. The jacketed hollow point design features a controlled-expansion cavity that opens reliably in soft tissue while resisting premature expansion when encountering heavy clothing or intermediate barriers. Boxer primers seat in reloadable brass cases, supporting future load development for shooters who roll their own defensive practice rounds.
