Has A Bit Of A Kick But Accurate

by Naturalist, Verified Owner from AZ, United States Written on September 22, 2025
I used the Underwood 10mm Auto 180gr Xtp Jhp ,in both an EAA Tangfolia Witness Standard and Compact pistols and had no issues with functioning. The Guns functioned flawlessly. At 20 yards they were very accurate and the grouping for 5 shots was about 2" inches and that was with a bit of flinching. The ammo had a bit of kick in my guns but I was able to manage the kick. I would definitely recommend this ammo.
Pros:
  • Functioned well
Cons:
  • Bit of a Kick
Best Used for:
  • Target / Self Defense
Would recommend: Yes

The Good Stuff

by Foot Hills Phil, Verified Owner from AZ, United States Written on September 3, 2025
No 40cal Short & Weak performance from this ammo. This is the good stuff. The 135 gn has the massive but abrupt energy dump on target but the 180gn has the penetration. This is the 10mm as 10mm was intended to be. a rival to the 41 Rem Mag in an auto pistol.

underwood ammo

by Michael Stewart, Verified Owner from GA, United States Written on July 9, 2025
The 10mm Underwood ammo I purchased for hunting is performing great. I did a lot of research and it came down to the underwood and the buffalo bore. Both seemed to perform equally (almost exactly) in the videos I watched. Needless to say I am not disappointed in the underwood. The FPS and velocity are higher than most and according to the chrono test is videos I watched, they also were within 50FPS of what the box said per 5 shots. This ammo is very well put together

Underwood loads full power 10 mml ammo

by James, Verified Owner from MO, United States Written on November 15, 2024
Underwood's one of these only companies that loads full power 10 mm ammo. I bought this ammo to try deer hunting with. I wanted the 200 grain but they were out of stock.

Real 10mm ammo

by wrenchman76, Verified Owner from IL, United States Written on October 31, 2024
Underwood is one of the few manufacturers that fully load 10mm to its full potential. Never disappoints me. XTP is a proven projectile. What I use for my everyday carry
