10mm Auto 135 Grain Jacketed Hollow Point

0.50 LBS

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. Very Impressed 5 Star Review

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

  2. Great Product 5 Star Review

    Great product, great company. The only place I will buy my ammo from now on.

  3. Top Notch 10mm Ammo 5 Star Review

    Posted by on 17th Jul 2016

    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!!

  4. Hot round 5 Star Review

    Posted by on 11th Jul 2016

    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.

  5. 10mm Glock 29 5 Star Review

    Posted by on 29th Jun 2016

    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.

  6. 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.

  7. 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!

  8. 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

  9. 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!

  10. Extreme! 5 Star Review

    Posted by on 26th Apr 2016

    Excellent personal defense round and functions flawlessly in a Glock 20
