Hornady is recognized for its precision in manufacturing brass, which is integral to their status as a leader in bullet production. They meticulously measure their brass for consistent wall thickness and test pressure calibration for uniform case expansion, ensuring each piece meets their high standards. Imperfections such as case mouth anomalies are common but are typically resolved in the first firing and do not affect case life or performance. For optimal use, new rifle brass should be prepared by straightening and deburring the case mouth, with lubrication on the case neck for the reloading process. This brass is new, unprimed, and not loaded ammunition.
