[QUOTE="budlight, post: 2137299, member: 2939"] This is why I went to 6XC over the 6BR. The BR is kinda limited to about 30 grains of powder. So it can't use slower powders. This follows more than two years of developmental work on the 6XC cartridge by Norma. Case head hardness of the new 6XC brass will be on par with the best and hardest commercially-manufactured cartridge brass. Hardness is important for best use in a repeating rifle, especially one used for NRA High Power and Long Range competition. The Norma standard for body wall runout is .002 inches or less at the base of the case. The new brass features a large rifle sized primer pocket. A detailed study of large and small rifle primers showed that large rifle primers worked best when the propellant charge exceeds 35 grains as is the case with the 6XC. Pressure data indicates higher attainable velocities compared to a standard .243 Winchester cartridge. The 6XC attains these higher velocities with less propellant and lower pressures (superior case design is the reason). The 6XC has dominated the across-the-course portion of the NRA High Power Rifle National Championships at Camp Perry as well as the NRA High Power Rifle Long Range events. Norma has high hopes for the 6XC as the next dominant ISU 300 Meter cartridge in Europe. Norma’s test shooter disclosed that his recent 6XC barrel had fired smaller groups than his previous ten 6BR barrels. [ATTACH type="full"]257435[/ATTACH] [/QUOTE]
