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.

I've been using your .41 max xtp for about 3 years, and have been asked by other .41 mag Blackhawk owners several times (especially new owners) what the best ammo is on the market for hunting, etc. and always refer them to Underwood. One of the questions that comes up is whether your ammo is safe for the Blackhawk or other .41 mags, given the advertised/demonstrated FPS & M.E. I tell them I've never had an issue in that regard, but it would be helpful if that was addressed on your site. in particular regarding SAAMI standards, for the .41 Mag and other calibers y'all offer.

I have been a customer for several years and have made many purchases of various handgun calibers for on & off duty carry. Ordering is as easy as it gets. Cust. service is great! Take advantage of free shipping offers & sales, shipping? My last order was on a Sat. night, late. I had my order on Monday morning! No kidding! Ammo is always fresh, clean packaged great. Never had a malfunction - ever! Shot in a variety of guns, from .38 spl. +P, 9MM, .357 mag., .41 Mag., .45 ACP., .45 Colt. None better! Thank you gang!

I hand loaded .41 mag for many years...this ammunition is as close to my heavy loads as I can imagine. The price was right on, the shipping was downright fast and the product looks great. I'll be back for more ! Great job from the Underwood's Family !

Underwood has hit another bases loaded home run with this ammo. The 41 magnum is my all time favorite after 45+ years of shooting. This ammo is clean burning, hard hitting, and extremely accurate. Nearly perfect round for personal defense. Cycle perfectly in my S&W 57, S&W Mountain Gun, and Ruger Blackhawk. I'll be back for more! Underwood is a superb company to do business with...great customer service and superb quality ammo.

Performance and price much better than any round found at local gun stores. I think I will try some 45acp from Underwood next.

The .41 magnum is truly a handloaders round...well I don't handload at the moment. After looking around for a bit I found these from Underwood, fantastic find! I have been running these through a 4" model 57 Smith and have been completely satisfied with the performance and accuracy of these rounds. Will purchase again, already have! :)
