The Underwood Ammo .40 S&W ammunition stands as a testament to precision engineering and reliability, designed for those who demand excellence in self-defense and hunting scenarios. This newly produced round is non-corrosive with boxer primed reloadable brass cases, ensuring longevity and consistent performance.
This particular cartridge features a bullet diameter of 0.4 inches and weighs in at an impressive 200 grains. The projectile leaves the barrel at a velocity of 1000 feet per second, delivering substantial stopping power with a muzzle energy of 444 foot-pounds.
Constructed from nickel-plated brass, this casing not only enhances durability but also ensures smooth feeding and extraction—a crucial factor during critical moments. As a subsonic round, it travels slower than sound itself, making it particularly suited for use with suppressors without compromising on its effective range or impact.
The lead bullet design boasts a sectional density (SD) of approximately 0.179—a measure that underscores its penetrating capability through various barriers while maintaining stability during flight due to its ballistic coefficient (G1). These attributes make it an exemplary choice when seeking reliable penetration combined with controlled expansion upon impact.

Whether you’re safeguarding your home or pursuing game in the field, rest assured that this ammunition delivers unparalleled performance where it counts most.
