Concentricity indicator - SINCLAIR INTERNATIONAL

We believe the Sinclair concentricity gauge is the easiest to use and most accurate gauge of its kind on the market. Accuracy for a lifetime of use, the Sinclair's concentricity indicator will accept cases up to 50 BMG. The Sinclair concentricity gauge is used to measure eccentricity by turning the case turn or loaded onto two sets of bearings which are captured in anodized aluminum blocks. These bearing blocks are longitudinally adjustable to allow for the case of different lengths or different lengths of loaded shots. The handloader can measure case sizes on the neck and measure rounds loaded on the neck or out on the bullet. The bearing blocks ride into a milled slot of the gauge base plate. This milled slot keeps the blocks in alignment with each other. This arrangement provides the best support for the cartridge, allowing the user to turn the cartridge smoothly. Large thumb levers on the bearing blocks quick and easy adjustments. The anodized base plate is extremely stable, allowing the user to take accurate readings. The indicator tower is designed to allow vertical and sideways adjustment of the dial indicator. The mounting block for the dial gauge is designed to accommodate dial gauges with standard 0.375 "mounts. This is a quality measuring tool for the serious precision reloader.
