AR-15 rifles eat a lot of ammunition, so reloading is a viable cost-saving operation. However, all military ammunition, an excellent source for reloading brass, has staked primers, which are difficult to remove. Many ammunition companies also stake the primers of commercial ammunition. As such, a bench tool like the Primer Pocket Swager is an excellent investment. The swager has a cast aluminum base, hardened steel cam, foam padded grip and a hardened steel rod that supports the case from inside to allow alignment with the swager head. It accommodates 22-caliber cases and larger, and comes with the RCBS limited lifetime warranty.
