Underwood Ammo’s 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.
As with all of Underwood Ammo’s 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.

This ammo is great it worked flawlessly in my glock 21 with the lone wolf 45-400 conversion barrel.it mushrooms quite nice and would make a great hunting round or personal defense round your choice.you won't find a cheaper or higher quality round than underwoods.
