Hornady 00 Buckshot .330 Diameter 5lb Bag Hornady Buckshot is cold swaged using a lead alloy hardened with antimony to prevent any potential deformities when fired. This allows the buckshot to fly straighter and to hit your target harder. Hornady uses a strict roundness tolerance of +0.001" in an effort to place more pellets on the target.
