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.

The bullet weight is right on and the speed is also right where they said it would be when tested. Shipping was fairly quick too using standard shipping. Very happy will be using them again till this Loser state stops it in June

Well made ammo--very impressed with quality. 135 gr ammo packs a major impact. in 10mm. Not recommended for deer, but believe it would be deadly @ 50yds on deer.. Waiting to try. Very please with fast shipping from Underwood.

After seeing reviews and YouTube videos, I had to give this load a chance. I shot this out of a G21 with a 5.2" LWD 10mm barrel and a 22lb spring. Even with the lighter weight of the g21 slide, the recoil on this round was very manageable with the heavier spring. I honestly couldn't tell a difference between it and the light-loaded plinking ammo (less than 500ft-lb loads). On top of that, it was dead-on accurate. I'll be adding cases of this ammo to my wishlist

I've been experimenting with different brands of 10mm ammo lately. Of the 8 different brands, I can honestly say Underwood is by far the best quality. I have tried their 220, 180, and this 135 grain. All have performed flawlessly. Underwood ammo makes your 10mm feel like a 10mm again. Recoil is strong, but not punishing. Accuracy is phenomenal. From now on, I will only run Underwood ammo through my gun.

Nice hot load with some snap and bark to it. I was very pleased at the results in my Glock 20.

Top Notch 10mm Ammo

I ordered the 135gr 10mm ammo. Man does it have some "snap" at 1600fps. This is the best Defense ammo at the best price and wow is it clean. I highly recommend this for no BS defensive ammo. It's GTG!!

I wanted to try a box of these to see how they would feed in my Kimber Custom TLE II with a compensator. After a whole box with no failures to feed I will be buying a lot more. My Kimber has a bushing compensator and the tremendous power from this ammo results in very little muzzle rise despite the obvious muzzle energy. I trust this ammo for my personal defense ammo.

I remember when candy bars were a nickel and twice as big as they are now. Underwood ammo is like that in today's market, and with the loads they offer I may stop handloading. I must have accuracy and fast shipping and get them both from Underwood.
Amazing product from a great company.

I can't say enough good things about this load. Hits fast and hard but still controllable. Prices are great too.
