(Examples: Glock, EA Witness)
Underwood Ammo’s 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’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.

No under powered FBI load here!

Full powered 10mm the way it's supposed to be. This is why I bought a 10 and underwood brings out its true potential.

great power and accuracy

I shoot an eaa witness and the 135 grain rounds were very accurate and did extensive damage to a deer's head at close range. Did run into a feed issue however. The edge of the copper jackets are sharp and catch the feed ramps. The 180 grain round has lead all the way to the edge and have fed perfectly.
10MM The way it was Designed

This is no underpowered round! It is a 10MM load that takes full advantage of the caliber. Highly recommend it!

Performed flawlessly in my Glock 20C. Clean burning full power loads that are extremely accurate. Fast shipping and great communication makes Underwood my #1 self defense ammunition.

My GLOCK G20 loves this stuff, FIRE/SMOKE ...sounds like a .357mag being fired. Turns heads at the indoor range I frequent. I will buy MORE ! You haven't experienced PURE entertainment untill you've shot Underwood Ammo in your G20 10mm

This load is enough punch for a 1 shot stop and has the lightest recoil of the entire 10 mm line. Great for duty work
