Action Shooters demand total reliability from their ammo and Hornady delivers! Like all Hornady ammo, our Cowboy rounds are engineered to perform flawlessly. Thanks to our swaged bullets, the projectile flattens at the target instead of fragmenting. Our propellants are the cleanestburning, and the diamond knurling means the bullet is lubed the entire length of the bearing surface. It all adds up to the highest quality ammo on the market.
