The 6mm XC was initially developed as a Wildcat cartridge specifically for NRA High Power match shooting by 11-time US National Champion David Tubb. The round originated from chambering a barrel using a .243 Winchester reamer held short, with the case reformed from .22-250. The round is optimized for bullets heavier than 100 grains to improve performance at long ranges - .243Win typically uses bullets lighter than 100 grains. It is touted as being one of the most accurate long-range 6 mm rounds in the world that is designed for repeating rifles.
The 6XC is now a CIP standardized case. The origin is listed as Sweden since Norma standardized the case. Factory brass is available from Norma and Peterson.
