10mm as intended
Posted by Josh on 17th Feb 2015
Matches (even surpasses) the venerable original Norma 200gr load for the 10mm. Couple that with the XTP bullet and you've got a load with devastating expansion and penetration. Runs fine in my stock Glock 20 Gen 4.
Great product! Great price!

694 ft. lbs. of muzzle energy! There are not too many semi-auto rounds that produce near 44 magnum energy but this round does. Highly recommended.
POWER I BET MY LIFE ON

This loading by Underwood is amazing. It is my go to woods carry load. I launched one of these 200 grain powerhouses, from a Glock 29, into a 150 lb wild boar at 40 yards. That pig rolled like he had been hit by a freight train! Great Job Underwood!

Clean burning and very accurate full power loads. My Glock 20C gobbles them up like jelly beans. Underwood will always be my #1 hunting and self defense ammunition. Thanks

These rounds performed flawlessly through my G21 that has been converted to 10mm. I don't have a chrono, but these felt A LOT stronger than any of the 45 ACP I used to put through the gun.

Very accurate in my Glock 20 with both 4.6" and 6" OEM barrels. Had some case bulging in my 6.6" Lone Wolf barrel?? No feed or extraction problems in any of them. Penetrated 4 one gallon water filled milk jugs (dimpled the 5th) with expansion at .651" from a distance of about 8' with the 6" barrel. I got soaked!! 2.5 " off-hand groups at 25 yards with the 6" Glock barrel which is what I keep on the gun. Moderate recoil.
Excellent full-power 10mm

This is extraordinary powerful accurate 10mm ammunition. Thanks, Kevin!
Very good ammo for hunting

This ammo is a hard hitting load has recoil but very manageable shot a 190 lb boar at 35 yards with my kimber eclipse he ran 10 and was down I would definitely recommend this ammo for sires hunters

Underwood 10mm 200grn XTPs are a good choice when heading to the woods. you have the great XTP bullet that holds up well at the high velocity Underwood runs them at.
only ammo I shoot
Posted by Rick on 7th Feb 2015
Upon diving into the 10mm world, I quickly realized there is no point in shooting 10mm unless you shoot these heavier loads. The stuff at your local gun store might as well be .40 or maybe .45 acp. Underwood, to this point, has been my go to for quality HOT ammo at a fair price. I've run through hundreds of rounds with no issues whatsoever. I will add this, however: I did have issues prior to purchasing an aftermarket heavier recoil spring. This ammo is too hot for the factory spring in my Glock 29. The Glock 20 handles it a little better, but I would advise a heavier spring for that gun as well. But this is to be expected. Increasing the recoil spring weight also allows you to take full advantage of the power of this round. The ammo runs relatively clean, as well. I'm going to try to not sound like an Underwood fanboy here when I say this ammo is a better alternative to other "hot" 10mm loads like Double Tap and Buffalo Bore. Double Tap's advertised velocities are embellished at best. Go to YouTube, and you can find quite a few videos comparing advertised velocities to actual velocities using a chronograph. Not to mention I have read quite a bit about quality control issues as of late. Buffalo Bore is solid, though, but it is more expensive than Underwood in my experience. This is the only 10mm ammo I will ever run.
