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.

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.

Powerful. Accurate. Powerful. Reliable. Powerful. Affordable...did I mention powerful?
Super hot ammo!

As usual, underwood pushes their ammo to the limits. It's considerably hotter than armscor, HSM, federal and other factory loads that I've tried.. I shot 5 rounds out of my scoped S&W 500 revolver and all five shots standing produced under 1.5 inches at 50yrds. Great round for big game or boat hunting. Moreover, the velocity and recoil from this ammo punches the palm of your hands; so don't shoot more than you have to lol. Excellent product and devastatingly powerful ammo for hunting or for scattering people away from the concussion at the range. Great job!
They kick HARD!

I finally shot these the other day and boy do they kick! They kick harder than 400g other brands out there. If you're looking for power and performance these are the ones.

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
