    $59.99
    Description:
    This thickness gauge from Insize Tools is an accurate, very fast and easy to use tool for measuring neck wall thickness. You can make multiple thickness measurements around a case neck in just a few seconds to determine the neck uniformity, or easily calulate a needed neck bushing size without having a loaded round. The gauge works with a spring loaded sliding anvil so the anvil pressure is always consistent, and comparing multiple measurements will be accurate. The ball anvil for case necks or tubing can be moved down to allow the gauge to measure flat stock up to 1 inch thick. Accuracy on the digital display is 0.0005 inch, with controls for on/off, zero and inch/millimeter. Comes in a Mfg: Sinclair International

The Sinclair Gauges are inserted into a fired, unprimed shortened case and then chambered into your rifle. The insert pushes back into the case when it contacts the end of your chamber. You then extract the case and measure the overall length. The gauge is made of 12L14 soft steel so it will not damage your chamber.
