Description

This ammunition is not to be used in Springfield Trapdoor rifles and its replicas/reproductions. 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 brass and features a unique nose that maximizes penetration and facilitates consistent and reliable magazine feeding. This round offers: Solid Brass (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 Brass 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. 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. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
