Dang Bill, nice review I was going to do a head to head with your results, But I just threw out my last 2 Dan Wesson Silverbacks.(insert extreme sarcasm now) You got off lucky my friend. I will be posting a version using the Rock Island 1911 w/ the same ammo and reloads and if my buddy will let me a 6" S@W 610 (the old one). I use Underwood ammo all the time 357 Sig/41 Mag ect. You get what u pay for

Ah yes, item#244, I currently have 5 boxes on hand, I used to have 10 but this stuff is just such a rush to shoot I couldn't resist. Underwood is by far the most meticulous maker of custom self defense ammunition operating today.
I dont have any ballistics gel so it was nice to find your testing here to see how it performs in that medium. As close as I can get are 1 gallon jugs of water with a heavy denim layer in front using 4 layers same as you guys. My test produced very similar results going through 4-5 jugs and denting or busting the front wall of the 5th or 6th jug. This round is simply brutal. I love 10mm. My test gun however was a 5"1911 platform Dan Wesson Silverback -
