Underwood .40 S&W 115 Gr. Lehigh Defense Xtreme Defender-Platinum Edition- Lead Free- Box of 20

The Xtreme Defender is based on the Xtreme Defense Fluid Transfer Monolithic (FTM) family of projectiles. The EXD projectile has optimized flute geometry, total weight, and velocity to achieve a penetration depth up to 18 inches* with a permanent wound cavity (PWC) that is just simply enormous; no expanding hollowpoint comes close to achieving anywhere near this collective volume of wound cavity. The non-expanding solid copper body ensures that common materials such as wallboard, sheet metal, and automotive glass will not affect the Permanent Wound Channel or capabilities of the projectile, unlike traditional hollow points.

The primary advantages of the Platinum Edition 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 casings with Underwoods new nickel plating process provide 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.

Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass. It was claimed that nickel-plated brass casings embrittled the brass therefore making it less desirable for reloaders despite the ease of cleanup that nickel plating offers. In addition, ammunition engineers raising concerns of using nickel plating in very hot +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass. 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.  This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Features:

• A permanent wound cavity (PWC) that is 2 times greater than any expanding bullet
• Reduced recoil
• CNC machined from solid copper to overcome barriers for consistent penetration
• Radial flutes that force the hydraulic energy outward due to massive pressure differentials
• Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers
