RCBS Case Master Gauging Tool

The RCBS 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.
