Underwood Ammo’s XTP rounds are notable for their power and accuracy. We utilize Hornady’s eXtreme Terminal Performance (XTP) bullets which are designed for deep terminal penetration, great accuracy and controlled expansion. We combine Hornady’s unparalleled XTP bullets with our own carefully formulated design which results in one lethal round.
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.

Underwood 350gr. 500 S&W ammo.is the 'Bomb'.
I obviously don't go to the range to shoot 300 rds.
of .50 ammo like I do 10mm &45acp.
All I can say is one fairly well placed shot will take out any 4 legged creature or two to three two legged criminals.

Nice round, even at the ranges (inside and outside).
Maintains POA very well at 100 yards.

Very accurate ammo out of a 4" barrel. Nice price for S&W 500 mag and shipping was very prompt.

Underwood ammo is the only ammo I've put through my s&w 500 magnum. This is a great product. Great price and great performance. This ammo is nothing but impressive. I've sent the 350 grain hollow point through steel plate with no problems. Will buy this ammo again and again
Accuracy is right on

I've been shooting your S&W 500 magnum loads and I am VERY happy with their performance. Accuracy is right on to the point of aim. They are better than a major manufacturer's loads, and at a lower price, including shipping.

Shot a opossum at 20 yards the other night. To say that the 350 grain 500 mag "vaporized" him would be a accurate statement. Can't wait to try this round on Hogs! Another SUPER product.

I have purchased from you in the past through Gunbroker, and a direct order. I recently fired some of your 44spl and S&W500 at the range, and I was very surprised at how accurate it is compared to other manufacturers' ammunition. Same gun, same shooter, far better groups.

I was very impressed with the accuracy & power this bullet provides... I have shot HSM, Winchester, Hornady, & several other factory loads & this is 1 of the best loads that I have purchased for the 500 S&W... Will buy again & would recommend

Accurate out of my 8 3/8" S&W 500. Could have camped out in the tunnels it was blasting in the moist clay berm:)
