Underwood 9mm Luger 105gr Maximum Expansion Ammunition - 20 Round Box
Lehigh's Maximum Expansion™ Technology is used to produce projectiles that create the largest wound channels of any bullet you can buy. These cavernous hollow points are designed to expand upon contact with a fluid-based medium through hydraulic energy. They do not expand on dry mediums like wood, drywall, bone, or sheet metal. The expansion process of Lehigh's Maximum Expansion technology is very different than that of a traditional lead jacketed bullet that expands when it comes in contact with a hard surface √¢‚Ç¨‚Äú we designed these bullets to expand where the expansion is needed and that is in the vital zone of your intended target.
Lehigh Maximum Expansion bullets expand with razor sharp petals positioned AND maintained at the largest diameter to provide the greatest cutting surface. Contrast this with a traditional jacketed bullet that expands and quickly mushrooms the nose back along the bullets shank once again reducing the diameter down to a less effective size.
Through design and testing, we can move the expansion point and maintain the expansion diameter exactly where required providing the optimum terminal performance.
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.
