The Case Master gauging tool quickly measures several important case and cartridge dimensions, including case neck concentricity, uniformity and thickness, as well as case length and bullet run-out. All are important to accuracy and safety. It also detects case head separation before symptoms are apparent on the outside of case. The tool is much quicker than a dial caliper and makes a tedious job simple and less tiring.
