About the .40 Super Cartridge

The .40 Super is a high-pressure cartridge designed to deliver performance that bridges the gap between the .40 S&W and 10mm Auto. It offers significantly increased velocity and energy compared to standard .40 S&W loads when fired from a properly converted firearm.

Because of its higher operating pressures, this cartridge should only be used in firearms specifically built or converted for .40 Super.

220 Grain Hard Cast Flat Nose – Why It Matters

The hard cast flat nose bullet is purpose-built for:

• Deep, straight-line penetration

• Minimal bullet deformation

• Reliable performance against tough barriers

• Hunting medium-sized game

• Backcountry or wilderness defense

Unlike hollow points that expand, hard cast bullets are designed to maintain shape, making them ideal where penetration is critical.

Performance & Applications

Best suited for:

• Backcountry defense

• Hog hunting

• Predator control

• Woods carry

• Experienced defensive shooters

Underwood is known for loading ammunition toward the higher end of performance specifications, making this round particularly appealing for those who want maximum ballistic potential from the .40 Super platform.
