Nosler 51181 40 S&W 150gr JHP Assured Stopping Power Ammo 50rd

The Nosler 51181 Assured Stopping Power ammunition delivers consistent terminal performance for 40 S&W platforms. This 150-grain jacketed hollow point load combines proven bullet design with precision manufacturing to maximize stopping effectiveness. Law enforcement agencies and civilian shooters rely on this ammunition for critical applications where expansion and penetration must be predictable.

What Makes This Different

Nosler's Assured Stopping Power line features controlled expansion hollow point bullets engineered for optimal performance in defensive scenarios. Unlike standard ball ammunition, these jacketed hollow points expand reliably while maintaining structural integrity through barriers. The 150-grain bullet weight provides excellent balance between velocity and momentum in 40 S&W chamberings, delivering consistent 12-18 inches of penetration in ballistic gelatin testing.

Key Features

• 150-grain jacketed hollow point bullet for controlled expansion
• Optimized powder charge for consistent velocities across temperature ranges
• Nickel-plated brass cases resist corrosion and aid extraction
• Compatible with all 40 S&W firearms including Glock, Smith & Wesson, and SIG models

This ammunition performs consistently in duty pistols, concealed carry firearms, and competition applications. The hollow point design expands reliably in soft tissue while maintaining penetration through heavy clothing and light barriers. Temperature stability ensures consistent point of impact from summer heat to winter cold, critical for year-round carry ammunition. The nickel-plated cases feed smoothly in semi-automatic actions and resist tarnishing during extended storage.
