Peterson Cartridge Match Grade Unprimed Brass Features The Peterson Cartridge Match Grade Unprimed Brass is manufactured on small batch production lines with a quality control process designed to catch inconsistencies before a case ever reaches a customer s bench. Each 7mm PRC case passes through multiple quality inspections during production which helps ensure uniform wall thickness and case weight from piece to piece. That consistency is what gives a handloader the confidence to work up a precise load without chasing variance between cases. Because the brass ships unprimed reloaders have full control over primer selection and can match the large rifle primer pocket to their preferred ignition source for a given load. The mouth and neck of each case are annealed during manufacturing which softens the brass in that zone and helps maintain consistent neck tension over repeated firings and resizing cycles. A beautifully polished exterior finish rounds out the case giving it a clean bright appearance right out of the box. Peterson Cartridge markets this brass as reloadable so it is built to hold up through many firings for shooters who reload rather than buy new brass every trip to the range. Sold in 50 count boxes chambered in 7mm PRC this brass is suited to long range precision rifle shooters who want to maintain match grade consistency all the way to the target.
