Hornady Brass is manufactured to extremely tight tolerances to ensure this critical element is as consistent as possible. Brass is the foundation of an accurate cartridge, not a commodity, Hornady takes greater care in its creation. Every single Hornady case, regardless of the lot in which it was produced, is virtually identical to other Hornady cases in the same caliber. For you, this means consistent concentricity, pressures, velocity and accuracy — every time. Benchrest shooters have long known that uniform case wall thickness is vital to accuracy. With Hornady, you’ll get more reloads from your brass.
