This Weatherby brass is produced exclusively by Norma precision and is made to match grade specifications. These brass cases may show some "discoloration" this is because of the annealing process. Annealing ensures proper hardness as well as flexibility to expand and contract for repeated firing and reforming. If you tumble the brass prior to loading you can remove most or all of the annealing.
