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. HOT! 5 Star Review

    Posted by on 14th Nov 2015

    Clocked at 1500+ fps out of my Glock 29! Very hot but manageable. I did use a stronger aftermarket recoil spring. Fun and surprisingly accurate round.

  2. Fire Breathing Dragon! 5 Star Review

    Posted by on 8th Nov 2015

    Tremendous performance out of my Glock 20. You know you've got a threat-stopper when you use this ammo. It's everything the old Super-Vel .357 mag. wanted to be.

  3. Underwood Smokes the Competition! 5 Star Review

    Posted by on 29th Aug 2015

    I've used many ammo varieties over the years and Underwood ammo is the best out there as far as I'm concerned! Accuracy and dependability it doesn't get any better . Thanks Underwood

  4. Love this for my Glock G40 MOS 5 Star Review

    Posted by on 26th Aug 2015

    Really like this load and it feels a bit more powerful than other Underwood 10mm loads. My G40 doesn't shoot it as tight as the heavier stuff so I will order a KKM barrel when they make them for the G40. That should tighten up the groups a lot. Love the ammo tho.

  5. WWhen the S@#$ hits the fan 5 Star Review

    Posted by on 19th Aug 2015

    Underwood is proud of this stuff. I'm not using it it to plinck with but the day I am going into a place where I know every round counts this is what I am filling my mags with.

  6. Back the brand 5 Star Review

    This stuff moves. Shoot it and see for yourself.

  7. HIGH QUALITY STUFF !! 5 Star Review

    Posted by on 9th Aug 2015

    Shot 40rds through a Glock 20 and let me tell yeh.. This is excellent quality! It's clean and accurate, my ideal for out in the woods and home defense. Will defiantly purchase more. A+

  8. Flat Shooting! 5 Star Review

    Posted by on 24th Jul 2015

    I bought this for use in my EAA Witness 5" barrel. ran flawlessly and shoots flat. I was shooting rabbits between 50-80 yards without having to change my point of aim. After shooting all the watered down factory loads from the competitors I am very impressed with the feel, power, accuracy, and performance of Underwood.

  9. 135 Grain HP 10mm 5 Star Review

    Posted by on 14th Jul 2015

    This is a pleasure to shoot even though it is a full-on 10mm load. Feeds perfectly in Glock 29 dn in a Dan Wesson Titan 1911.

  10. Glock 29 Gen R 5 Star Review

    Posted by on 13th Jul 2015
