Hornady Case 270 Win UnprimedTight Wall ConcentricityConcentricity helps to ensure proper bullet seating in both the case and the chamber of your firearm. Higher concentricity also aids in a uniform release of the bullet on firing, for optimal velocity and accuracy. Uniform Case Wall ThicknessBenchrest shooters have long known that uniform case wall thickness is vital to accuracy. We manufacture to extremely tight tolerances to ensure this critical element is as consistent as possible. More Reloads per CaseWe treat Hornady brass as the foundation for an accurate cartridge, not a commodity. Because we take greater care in its creation you’ll get more reloads from Hornady brass. Consistent Weight and CapacityEvery 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 pressures, velocity and accuracy — every time.
