Sierra Outdoor Master .40 S&W 180gr JHP Defense Ammo 20Rd Box A8460-28

The Sierra Outdoor Master .40 S&W 180-grain Jacketed Hollow Point (JHP) load delivers serious, match-grade reassurance for personal defense and pistol-caliber carbines (PCCs). A major headache with standard defensive handgun ammunition is that hollow points can expand erratically or fail to open at all at subsonic speeds, leading to dangerous over-penetration. Sierra eliminates this risk by using its premium Sports Master JHP bullet, featuring Power Jacket skiving geometry to ensure immediate, symmetrical mushrooming and maximum energy transfer upon impact.

The technical advantage centers on a perfectly balanced jacket-to-core relationship. Built with an ultra-concentric copper jacket and a voidless lead core, this heavy-for-caliber 180-grain projectile is perfectly tuned to stabilize in standard .40 S&W barrel twist rates. The mouth of the hollow cavity is lined with specialized pre-cut skives (relief cuts). The split-second these skives touch a target, they force the jacket to peel back uniformly, dumping the round's kinetic energy instantly into the threat while keeping the core intact for controlled, reliable penetration.

Cruising at a subsonic 985 FPS, this load strips away the harsh, snappy recoil often associated with the .40 S&W caliber, allowing for lightning-fast, accurate follow-up shots. Every round is loaded into premium, reloadable brass with clean-burning powders to ensure 100% reliable feeding, cycling, and extraction in both modern defensive pistols and semi-automatic carbines. Whether it is your primary carry gun or a home-defense setup, this load provides the sub-MOA accuracy and devastating terminal performance required when it matters most.

Key Benefits

• Power Jacket Skiving Geometry: Precision-cut jacket skives ensure rapid, predictable, and symmetrical expansion at subsonic velocities.
• Heavy-For-Caliber Momentum: The 180-grain weight maximizes energy transfer and downrange stopping power while softening felt recoil.
• PCC & Handgun Optimization: A smooth nose profile and uniform dimensions ensure flawless feeding and cycling in both pistols and carbines.
• Anti-Over-Penetration Design: Rapid mushrooming dumps kinetic energy inside the target, minimizing close-quarters safety risks.
