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.

Top Notch 10mm Ammo
Posted by Rob 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!!

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.

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.
Amazing product from a great company.

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

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!

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
FUNNY 'N FAAAAST

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!

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.
