Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge builds this 6mm ARC brass as unprimed reloadable rifle casing designed to maintain the match grade consistency the brand is known for throughout every stage of manufacturing. The cases are sized for small rifle primers giving reloaders a clear defined specification to work from when selecting components. Small batch production runs allow Peterson s quality control process to catch inconsistencies before cases ever reach a customer s reloading bench. This attention to process is what lets precision shooters trust that one case will perform the same as the next across an entire batch. Each box contains 50 cases a count suited to developing and testing loads without committing to a full case purchase up front. Reloaders working up precision loads for a 6mm ARC rifle depend on consistent brass to isolate variables like powder charge and seating depth during load development. Because the brass is fully reloadable it can be resized and reused across multiple reloading cycles once a load is finalized. Peterson Cartridge s match grade standard gives 6mm ARC shooters a dependable foundation for building ammunition intended to hold tight groups downrange.
