Underwood Platinum Edition 10mm Auto Ammo 140 Grain Lehigh Xtreme Penetrator Lead Free Box of 20

Underwood Ammo™ combines our trademark power and precision with Lehigh Defense masterfully designed Xtreme Penetrator bullets – the 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.

The primary advantages of this coating are as follows:

• Improved Corrosion Resistance of the Copper:  There will not be any oxidation (brown spots) or darkening of the copper projectile over time or extended storage.  In aggressive applications such as wet, humid and even salt water, the coating will protect the copper from oxidation or verdigris.  This is very beneficial for self-defense ammo that is often purchased and stored for use for extended periods of time.
• Improved Lubricity & Enhanced Feeding:  The finish provides excellent dry-film lubrication that helps with feeding in all actions of firearms.  The coating is very forgiving on modified guns since it reduces the friction of the projectile against the feed ramp as well as the chamber entrance.
• Reduced Barrel Wear:  The coating reduces barrel wear over a standard monolithic projectile.

Nickel-plated brass casings, their 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.

As with all of Underwood Ammo rounds, they utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

While taking advantage of their state of the art testing equipment, this high-performance ammunition is field tested using popular, real firearms that their customers are most likely to own out in the real world with all the elements you would experience.

This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
