21st Century - Tool - Concentricity gauge

The new concentricity gauge from 21st Century Shooting uses a horizontal dial test indicator. This type of gauge was designed specifically for checking rotating diameters and in fact is exactly the type of gauge used in the machining industry for decades to measure run out – the very thing that we as hand loaders are striving to minimize or eliminate.

Additionally, this new gauge uses Stainless Steel TURNING ROLLERS as opposed to fixed bearings or V configuration. Also the 21st Century Shooting gauge lets the operator check not only the O.D. but the I.D., a feature exclusive to the 21ST CENTURY SHOOTING CONCINTRICITY GAUGE. You will especially appreciate the roller supports that glide on linear guide-ways, with a simple push of a button for adjusting the base. No tools necessary.
