Underwood 357 Sig 147 Grain Hornady XTP Jacketed Hollow Point Box of 20

While taking advantage of state of the art testing equipment, this high performance ammunition by Underwood is field tested using popular, real firearms that 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, Underwood stands by their product 100% and will make sure the customer is satisfied with every purchase. This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.
 
Hornady XTP bullets were designed for hunting, self-defense, and law enforcement. One of the great things about the XTP bullet is reliable performance, it features controlled expansion where six serrations divide the bullet into six symmetrical sections. These sections weaken the jacket to allow controlled expansion at low velocities and ensures fragmentation does not occur at high velocities. The XTP bullet is really known for its stopping power. They were designed from the beginning to expand reliably at a variety of handgun velocities and deliver deep, terminal penetration with every shot. Most handgun bullets are designed to perform at a single factory-specified velocity where the XTP bullet is designed to offer controlled expansion over a range of velocities. Each XTP Bullet has a swaged core and drawn copper jacket to ensure uniform expansion and in-flight stability. Adding a cannelure to this bullet keeps the core and the jacket locked together while also allowing the cartridge case to tightly crimp, adding security at high velocities. All of Underwood Ammo rounds utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
 
The Underwood nickel plating process provides several key benefits 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.
