Product DescriptionThe key to loading the most accurate ammunition possible is to keep everything as precise as possible. The Case Master Gauging Tool can easily measure neck concentricity, uniformity, thickness, case length and bullet run-out. All of these measurements are important to get reloading equipment set up to produce the most accurate rounds. This tool will also aid in detecting case head separation before any symptoms are apparent on the outside of the case.
