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.

Excellent personal defense round and functions flawlessly in a Glock 20
Violent Energy Transfer
Posted by Freedom Lover on 24th Apr 2016
I purchased a box of these along with 4 other Underwood 10mm loads to test for a video series. In water jugs these 135s stop in only two jugs but make by far the largest explosion of water in the entire test. In the cinder blocks they made the largest entry hole through the first wall but had no energy left to damage the second. All of the Underwood Ammo functioned perfectly and shot to point of aim.

Just went behind our house to shoot my flip steel target today . I started out with the Rem 180gr fmj . They were ok at flipping the spinner ,but these underwood 155gr jhp knocked the whole thing over 3 times in a row until I got a hammer and pounder it all the way down . It spun it multiple times , when the Rem 180's would flip it 2 maybe 3 times . This will make a great carry load.

I couldn't wait to get my hands on this ammo, after seeing all the videos on YouTube. The 1600fps is just smokin, and the recoil is very manageable. Underwood ammo is the only ammunition you should get for your 10mm. It feels really good coming out of my Glock 20 Gen 4. I've compared different companies, and Underwood is definitely has the hottest rounds in every grain. Really love this ammo, ordered more in different grains.
Quality ammo- protect those you love

Been around guns all my life - almost 60 years old now.
-Goes bang every time the trigger is pulled.
-Lesson learned from years of handloading lighter projectiles recoil less. The 135 grain 10mm is an excellent home defense choice in my opinion. Recoil isn't excessive for my wife or myself so accuracy is enhanced.
-125 grain .357 magnum has statistically been the top fight stopper historically. The 135 grain 10 mm should also perform well in the defensive ammo role.
Quality - Best I've seen. Consistent function, Groups well, and point of impact. Ducta-Bright 7a Nickel plating must be seen/felt to understand the value. It definitely enhances smooth feeding and extracting of the case.
Can't go wrong

If you like your accuracy and consistency then you can't go wrong with Underwood ammo. 14 shots 25yrds 4in group, 14 shots 50yds 5.25in group, and 10 shots 100yrds 7in group all shot free hand with no supports. Can't beat Underwood ammo. Awesome

I run this ammo through my Glock 20 with a ported barrel and I'm impressed. You know that it's not a 9mm,40,45, ect when these come screaming out of the barrel.

Best 10mm ammo I have shoot yet. Ordering more today.
Underwood Scores High
Posted by Steve on 31st Jan 2016
Finally got my Glock 29, 10mm! Replaced the barrel with a Lone Wolf stock barrel, replaced factory 17lb recoil spring with a tungsten extra power 21lb recoil spring, replaced Glock sights with Trijicon night sights and finally exchanged the standard 29 Glock 10 rd magazine with the standard Glock 21 13 rd magazine fitted with a magazine sleeve and BOOM, this guy is completely satisfied with the results. The Underwood 135 Jacketed Hollow Point is wicked hot & accurate! I use it exclusively at the range and concealed carry! Only brand I shoot!!
