Underwood Ammo’s XTP rounds are notable for their power and accuracy. We utilize Hornady’s eXtreme Terminal Performance (XTP) bullets which are designed for deep terminal penetration, great accuracy and controlled expansion. We combine Hornady’s unparalleled XTP bullets with our own carefully formulated design which results in one lethal round.
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.

Best 10mm ammo!
Posted by Dave on 7th Apr 2015
Underwood has the best full power 10mm ammo to be found at any price,and the fact that it cost less than any of the other full power brands (buffalo bore,double tap,grizzly) makes it a no brainer. I got the 200 grain xtp for woods carry in my glock 20 and have been very pleased with its power and weight retention. Super fast and friendly service,premium full power 10mm ammo,you cant go wrong!
A 10 mm as it should be

High quality ammo with a great bullet. Extremely consistent. Five shots over the chrono averaged 1215 fps with a sd of only 7 fps.
Best ammo I have ever shot!

it's been so hard to find 10 mm Auto full power loads with a good selection at a reasonable price that I can't even believe that I found Underwood ammo! they are by far the best ammunition providers I have ever seen, from the quality to the price and service there is no better company to deal with. I am so stoked as a 10mm auto enthusiast to have found such a selection of full power loads with quality bullets at a reasonable price, I swear I'm dreaming!

10mm as intended

Matches (even surpasses) the venerable original Norma 200gr load for the 10mm. Couple that with the XTP bullet and you've got a load with devastating expansion and penetration. Runs fine in my stock Glock 20 Gen 4.
Great product! Great price!

694 ft. lbs. of muzzle energy! There are not too many semi-auto rounds that produce near 44 magnum energy but this round does. Highly recommended.
POWER I BET MY LIFE ON

This loading by Underwood is amazing. It is my go to woods carry load. I launched one of these 200 grain powerhouses, from a Glock 29, into a 150 lb wild boar at 40 yards. That pig rolled like he had been hit by a freight train! Great Job Underwood!

Clean burning and very accurate full power loads. My Glock 20C gobbles them up like jelly beans. Underwood will always be my #1 hunting and self defense ammunition. Thanks

These rounds performed flawlessly through my G21 that has been converted to 10mm. I don't have a chrono, but these felt A LOT stronger than any of the 45 ACP I used to put through the gun.

Very accurate in my Glock 20 with both 4.6" and 6" OEM barrels. Had some case bulging in my 6.6" Lone Wolf barrel?? No feed or extraction problems in any of them. Penetrated 4 one gallon water filled milk jugs (dimpled the 5th) with expansion at .651" from a distance of about 8' with the 6" barrel. I got soaked!! 2.5 " off-hand groups at 25 yards with the 6" Glock barrel which is what I keep on the gun. Moderate recoil.
