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.

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.

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'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.

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

Hard to beat the power of this 10 mm ammo. I wish it was offered in bulk for better cost.

These jxp 10mm rounds seem pretty good. I haven’t shot them yet but they look and feel nice. Id definitely buy them again.
