The .308 Win SRP (small rifle primer) Cartridge is manufactured on Peterson Cartridge’s new, state-of-the-art case line which uses cutting-edge technology to produce some of the most precise and consistent casings on the market. Peterson Cartridge Co is committed to producing Match-Grade Brass that enables our customers to get more reloads per casing than industry average. This is also manufactured with a undersized flash hole measuring 0.060". Which will require you to use a undersized decapping pin (<0.059").
