Made in the U.S.A.

Match-Grade is a standard that must be held throughout the entire process of manufacturing some of the most consistent, accurate, and durable brass rifle casings available today. From Peterson's small batch production lines to their quality control department, to your bench, and on to the range. Match-grade is the standard that Peterson strives to achieve so that customers can maintain that standard all the way to the target.

Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.

This is not loaded ammunition.
