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 hollowpoints.
*Falling within FBI guidelines
This round offers:
⦁ Flutes that force fluid inward to build hydraulic energy and expel it radially.
⦁ Consistent penetration and wounding performance despite encountering barriers via monolithic material and non-expanding design.
⦁ Lightweight – high energy, low recoil
⦁ It does not rely on deformation for resistance in soft tissue, thus eliminating concerns of over-penetration resulting from a lack of expansion.
⦁ Barrier Blind - minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers
⦁ Streamlined manufacturing process over original CNC design.
Nickel-plated casings with our 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 therefor 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, we 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 our state of the art testing equipment, this high performance ammunition is field tested using popular, real firearms that our customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, we stand by our product 100% and will make sure the customer is satisfied with every purchase.
