Hornady New Unprimed Brass .300 Win Mag Cartridge Cases, 50 count - 8670

Overview

Hornady .300 Win Mag brass cases are produced to ensure consistent wall thickness, weight, and internal capacity. Each piece of brass undergoes pressure calibration testing to confirm uniform case expansion during firing. This precision manufacturing process ensures tight wall concentricity, which facilitates proper bullet seating and reliable pressure characteristics. These are new, unprimed cases. Because of the final tumbling and annealing process, some cases may exhibit minor cosmetic imperfections, such as a pinkish hue on the neck or minor dents in the mouth, which are typically resolved after the first firing. It is recommended to perform standard brass preparation—including straightening case mouths, chamfering, and deburring—before initial use.
