The CaseMaster is a multi-purpose gauging tool which will measure case neck concentricity, uniformity and wall thickness, case length and let run-out. Impending case head separation can be detected before obvious lines appear on the outside of the case. Measurements are displayed on a .001 inch dial indicator (included), adjustable V Blocks accommodate most any length case securely and the compact base doesn’t take up much room on your bench.
