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