Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge builds this .243 Win brass to a match-grade standard maintained from the first stage of manufacturing through final quality control. Small batch production lines allow tighter tolerances than typical mass-production brass giving handloaders more consistent case capacity and neck tension round to round. That consistency translates directly into tighter velocity spreads and more predictable accuracy at the bench and on the range. Every case ships unprimed and ready for the reloader to select their own primer and load. This brass is cut for small rifle primers and carries a 0.060 inch flash hole noticeably smaller than the 0.080 inch flash hole used on Peterson s large rifle primer brass. Reloaders need an undersized or X-small decapping pin to properly deprime these cases without damage. The cases are fully reloadable letting handloaders get multiple firings out of each one when loads are kept within safe pressures. Sold in boxes of 50 this Peterson Cartridge .243 Win brass suits reloaders who demand match-grade consistency from their components.
