Nosler 51279 Assured Stopping Power 40 S&W 180 gr JHP Ammo - 20 Rounds Per Box

Nosler 40 S&W ammo loaded with 180-grain jacketed hollow point bullets strikes a solid balance for defensive and range shooting. This is purpose-built ammunition from a maker known for obsessing over consistency—each round benefits from Nosler's fastidious quality control, including hand-inspected brass, verified powder charges, and polished finished rounds. If you're running a duty or carry load in .40 S&W and want ammunition you can trust, Nosler's reputation for precision manufacturing carries over from their match-grade rifle ammo into their handgun offerings.

The 180-grain JHP arrives at 1005 fps muzzle velocity and 404 ft-lbs of muzzle energy—a moderate, controllable load suited for indoor range work and standard-pressure practice. Nosler brass forms the foundation of every cartridge, dimensionally verified and properly prepared to ensure reliable chambering and consistent performance across your magazines and firearms.

Twenty rounds per box means you get a practical training or qualification pack without overbuying. Whether you're zeroing a new carry gun, logging range time between matches, or building a reliable duty load, Nosler's attention to detail means you're not guessing on what's in the box—it's built to the company's documented standards, not loose industry minimums.

Specifications

Frequently Asked Questions

What's the difference between this and standard factory .40 S&W ammo?

Nosler subjects every component and finished round to stricter inspection than typical factory ammunition. Brass is verified for correct length, neck-sized, and flash holes checked for alignment. Powder charges are individually weighed rather than speed-dropped, and all rounds are visually inspected and polished before packaging.

Is this ammo suitable for carry or defensive use?

This ammunition uses a jacketed hollow point bullet design. However, ammunition selection for carry should reflect your specific firearm, local laws, and training. Consult your firearm's manual and legal counsel before adopting any load for self-defense.

Will this work in all .40 S&W firearms?

This is standard .40 S&W ammunition and should chamber in any firearm chambered for that caliber. Always verify your firearm's manual and test any new ammunition load in your specific gun before relying on it.

How many rounds do I get per box?

Each box contains 20 rounds, making it a convenient unit for practice sessions, qualification courses, or rotation of carry ammunition.
