The 6mm XC is a precision rifle cartridge designed primarily for competitive target shooting, particularly in disciplines like benchrest and long-range shooting. It was developed by renowned shooter David Tubb and the company Superior Shooting Systems. The 6mm XC offers a blend of high velocity, accuracy, and manageable recoil, making it a popular choice among competitive shooters. Typically, it is loaded with bullets in the 90 to 115-grain range, offering excellent ballistic performance and flat trajectories.
The cartridge's design allows for efficient powder burning and higher ballistic coefficients, which contribute to its long-range precision. It is often compared to the 6mm Creedmoor and 6mm BR (Bench Rest) cartridges, though each has its specific advantages depending on the context of use. The 6mm XC is particularly praised for its minimal wind drift and consistent performance in varying conditions.
Overall, the 6mm XC is esteemed in the precision shooting community for its accuracy, consistency, and effectiveness in competitive environments.
