Nosler 51279 ASP 40 S&W 180gr JHP Defense Ammo 20 Rounds

The Nosler 51279 Assured Stopping Power ammunition delivers consistent terminal performance through precision-engineered 180-grain jacketed hollow point bullets. This 40 S&W load combines Nosler's proven bullet technology with carefully selected propellants for reliable expansion and penetration in defensive situations.

What Makes This Different

Nosler's Assured Stopping Power line features bullets specifically designed for maximum stopping power rather than target shooting. The jacketed hollow point construction ensures controlled expansion while maintaining weight retention, unlike standard ball ammunition that may over-penetrate. Each cartridge undergoes quality control testing to maintain consistent velocities within 25 fps, providing predictable performance shot after shot.

Key Features

• 180-grain jacketed hollow point bullets engineered for controlled expansion
• Premium brass cases with consistent wall thickness for reliable feeding
• Boxer primers suitable for reloading applications
• Velocity optimized for standard 4-inch barrel lengths
• 20 rounds per box packaging for convenient range sessions
• Compatible with all 40 S&W chambered firearms
• Nickel-plated cases resist corrosion and enhance visibility

This ammunition performs consistently across temperature ranges from -20°F to +125°F, maintaining reliable ignition and velocity. The 180-grain bullet weight provides substantial momentum transfer while generating manageable recoil in full-size and compact pistols. Law enforcement agencies and civilian shooters rely on this load for duty carry and home defense applications where reliable stopping power remains paramount.
