Winchester Unprimed Brass Handgun Cartridge Cases 100/ct .357 Mag

The brass cases undergo annealing during manufacturing to achieve the proper hardness, ensuring the bullet is held securely while maintaining the necessary flexibility during firing. Users should note that the cases may exhibit a light stain near the neck due to this process.

Reloaders should inspect the case mouths upon receipt, as some may have imperfections from manufacturing or shipping. Proper resizing, chamfering, and deburring of the case mouth are recommended before use. An expander ball can be used to align the neck with the sizing die if desired.
