Product Description

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.

Nickel plated casings with our new nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading.  Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.
 
Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass.  It was claimed that nickel plated brass casings “embrittled” the brass therefor making it less desirable for reloaders despite the ease of cleanup that nickel plating offers.  In addition, ammunition engineers raising concerns of using nickel plating in “very hot” +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.

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.

  1. Amazing product from a great company. 5 Star Review

    Posted by on 21st May 2016

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

  2. These things bark! 4 Star Review

    Posted by on 14th May 2016

    A real head turner while shooting. Feed great through my Gen 3 G20sf. Real deal round at surplus prices. Keep up the good work Underwood!

  3. Smokin fast 5 Star Review

    Posted by on 11th May 2016

    Fired the 135gn, 165gn gold dot, and the 115gn extreme defender at three old road signs I had which were spaced 2" apart and backed with a gallon water jug. All three rounds punched through all three pieces of metal, exploded the water jug and kept going. Firearm was the Glock 49 MOS

  4. FUNNY 'N FAAAAST 5 Star Review

    Posted by on 30th Apr 2016

    Although I just received this ammo and haven't had a chance to use it yet I must still give it a FIVE STAR rating based on a published 135 grain Noslerl at 1667 from my six inch Glock. The capper is the warning on the box. It is actually a "health warning " about the dangers associated with lead. All this time I thought that that the decidedly obvious health detriment was the whole reason to actually use "Gucci" bullets! Got to love an outfit with a great sense of humor. Underwood is the new Lee Jurras of this century. I am certainly going back for more of his "dangerous" lead!

  5. Extreme! 5 Star Review

    Excellent personal defense round and functions flawlessly in a Glock 20

  6. Violent Energy Transfer 5 Star Review

    Posted by 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.

  7. the good stuff 5 Star Review

    Posted by on 14th Mar 2016

    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.

  8. As advertised!!! 5 Star Review

    Posted by on 14th Mar 2016

    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.

  9. Quality ammo- protect those you love 5 Star Review

    Posted by on 2nd Mar 2016

    Been around guns all my life - almost 60 years old now.
    Trust:
    -Reliable function.
    -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.

  10. Can't go wrong 5 Star Review

    Posted by on 16th Feb 2016

    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
