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.
This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

My CZ SP-01 loves this ammo. Hits hard and very accurate. Recoil is stout, but managable. I use Underwood for all my personal defense ammo, great stuff.

1270 fps in 16" barrel

I recorded the following 5 shot averages at 15 feet using a ProChrono rounded to nearest 5ft. -16" Kel Tec Sub2000 1270 fps for 645 ftlbs -6" Glock G24 1140 fps for 519 ftlbs -5.3" Glock G35 1135 fps for 515 ftlbs -3.5" Glock G27 1035 fps for 428 ftlbs -3.1" Kahr PM40 1020 fps for 416 ftlbs These rounds seem best suited for pistols when needing deep penetration or barrier blind performance. For all-round carbine use choose the 155gr XTP as it has the highest energy and best ballistics from 100-300 yards.
