Underwood Ammo 10mm 140 Gain XTREME Penetrator Ammunition, 20 Rounds Per Box Md: 648
Underwood Ammo combines our trademark power and precision with Lehigh Defense™ masterfully designed Xtreme Penetrator bulletsóîthe result is one jaw dropping round. This round is solid copper and features a unique nose that maximizes penetration and facilitates consistent and reliable magazine feeding.
This round offers:
- Solid Copper (Lead Free) precision CNC machined design. Good for the environment, bad, really bad for the target
- Unique nose that increases the hydraulic velocity creating high pressure spikes resulting in a larger permanent wound column and over twice the penetration than most expanding bullets.
- Blunt nose for initial energy transfer and straight, deep penetration while allowing for reliable magazine feeding.
- Solid copper construction and cutting edges to punch through entry barriers without deformation or deflection.
Nickel plated casings with our new nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 10mm Automatic is a powerful semi auto cartridge. With the proper bullet in capable hands it is suitable for hunting medium size game at close range. Although it has been used on large dangerous game including Cape buffalo and the great bears it is not ideal for such game. The round is capable of pushing a 180 grain bullet to 1,300 FPS from a 5” barrel. This exceeds the power of a .357 magnum by a good margin and is closely on the heels of a .41 magnum. Bullets are .400” diameter and range from 125 grains to 220 grains. Once in service with the FBI, it is now considered excessive in recoil and stopping power for law enforcement use. Hand guns and ammunition is available from most major manufactures.
