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.

    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

  4. Impressive ammo 4 Star Review

    Posted by on 21st Nov 2016

    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.

  5. ACCURATE 5 Star Review

    Posted by on 7th Nov 2016

    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

  6. Top quality 5 Star Review

    Posted by on 29th Oct 2016

    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.

  7. Very Impressed 5 Star Review

    Posted by on 20th Sep 2016

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

  8. Great Product 5 Star Review

    Posted by on 15th Aug 2016

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

  9. 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!!

  10. 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.
