The Nosler Assured Stopping Power (ASP) .40 S&W 150-grain Jacketed Hollow Point (JHP) Skived Jacket Brass 20-round box is a high-performance centerfire defensive cartridge engineered specifically for personal protection, concealed carry, law enforcement duty use, and home defense. A primary failure point in traditional defensive handgun ammunition is erratic bullet expansion or under-expansion caused by rigid jacket walls and velocity decay out of shorter barrels. Nosler resolves these operational performance limitations through its ASP series skived hollow-point technology, which features precision-cut jacket notches that trigger uniform, symmetrical petal expansion while preserving structural integrity and core retention.
The core technical advantage relies on the 150-grain ASP JHP projectile design. Featuring a skived copper-alloy jacket with pre-cut impact notches, the bullet utilizes these mechanical stress points to initiate immediate, reliable mushrooming upon hydraulic contact with soft tissue. This engineered deformation rate prevents surface fragmentation, holds the lead core firmly in place, and regulates penetration depth to maximize energy transfer and create a wide permanent wound channel. The smooth nose profile ensures seamless, snag-free feed ramp travel in compact, subcompact, and full-size semi-automatic handguns.
Launching its lighter, fast-moving 150-grain JHP projectile at a factory-rated 1,110 FPS muzzle velocity (generating 410 ft-lbs of muzzle energy), this ASP load provides a flatter trajectory and reduced felt recoil impulse compared to heavier 180-grain defensive offerings. Assembled using premium reloadable virgin brass cases, clean-burning propellants, and non-corrosive Boxer primers, the cartridge delivers uniform chamber pressure curves, smooth chamber sealing, and clean, positive extraction. It serves as a dependable defensive selection for shooters seeking manageable recoil paired with stopping power.
