Underwood Ammo(TM) standard Jacketed Hollow Point rounds are unrivaled. We use Nosler bullets which feature a tapered copper alloy jacket which extends to the rim for increased feeding and reliability. These rounds are also characterized by a form-fitted pure lead core, which allows for reliable expansion and maximum accuracy. As with all of Underwood Ammo(TM) 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.
