Underwood Ammo’s XTP rounds are notable for their power and accuracy.

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.

Should be a good Whitetail round, acceptably accurate to about 80 yards from my 7 1/2" Blackhawk

Great ammo; great price.

Ordered 100 and have only shot 20 so far. I wanted to try them during Michigan's deer season which starts tomorrow. Good that my order arrived so quickly; had time to check my sights, and run a few over the ShootingChony. 1264fps from 6½" Super Blackhawk (454) and 1533 from the 16" Rossi. That's pretty close to the 300XTP from a full-power Casull loading. So yeah...a 45Colt load that (from a longer barrel) competes well with my best .454 loads.
I like that!

This is very powerful, but very manageable in my new Ruger 4.2 inch Redhawk! Just awesome ammo. Underwood is the best...ordered at midnight on a Monday and received it on Wednesday morning! I use Underwood in .380acp, 9mm, and 45Colt and plan to get 45acp soon.
Best hunt load for 45 colt

For dangerous game go with the hard cast and between the two; you've got your 45 colt needs covered.

Theswe are reliable and consitent. They do pack a punch. My self-defense Bear Round for Alaska!

This is an extremely effective load for large game up to and including buffalo. A flat point hard cast gives excellent penetration and wound channels that stop large game quickly. A very accurate load in my revolver.
