BRAND: UNDERWOOD AMMO SKU:132 TECHNICAL INFORMATION Caliber: 9mm Luger Bullet Weight: 124 Grains Bullet Style: Speer Bonded Jacketed Hollow Point Case Type: Ducta-Bright 7a Nickel Plated Brass BALLISTICS INFORMATION Muzzle Velocity: 1300 fps Muzzle Energy: 465 ft lbs Underwood Ammo™ bonded rounds are unrivaled in power and precision. We utilize Speer bonded bullets which employ an exclusive Uni-Cor process where they bond the jacket to the core one molecule at a time. This essentially eliminates core-jacket separation, maximizes weight retention, and allows for unparalleled penetration and controlled yet fatal expansion. 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. 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.
