Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge builds its unprimed rifle brass to a match-grade standard maintained throughout the entire manufacturing process from small batch production lines through final quality control inspection. Each 7mm STW case is designed to accept a large rifle primer giving handloaders a consistent starting point for developing precise loads. The brass is made in the United States reflecting Peterson s commitment to domestic production and consistent material sourcing. Multiple quality inspections throughout manufacturing help ensure that every case in the box meets the same tight dimensional tolerances. The case mouth and neck are annealed during production a heat-treating process that relieves brass hardness buildup and reduces the likelihood of neck splits during repeated firing and resizing. This process extends usable case life letting handloaders get more reloading cycles out of each piece of brass before it needs to be retired. A beautifully polished finish on each case reflects the attention to detail Peterson applies to every batch. Sold in boxes of 50 this Peterson Cartridge 7mm STW brass gives serious handloaders the reloadable match-grade starting material their load development demands.
