Product Overview

The Sinclair International Concentricity Gauge with Dial Indicator is a precision measuring tool built for handloaders who demand accurate runout data on ammunition. Whether you're working with rifle cases up to 50 BMG or loaded rounds, this gauge lets you identify and eliminate concentricity issues that degrade accuracy and consistency. It's the kind of tool that separates dialed-in loads from good-enough loads, and serious reloaders rely on it to catch problems before they waste powder and primers on unreliable ammunition.

The design centers on two bearing block assemblies that cradle your case or loaded round, letting you spin it smoothly under a dial indicator to measure runout on the case neck, the bullet ogive, or anywhere in between. Those bearing blocks are held in a milled slot on the anodized aluminum base plate, keeping them in perfect alignment so your readings stay true. Large thumb levers make it simple to slide the blocks along the base to accommodate different case lengths or varying loaded-round dimensions—no tools required, just quick manual adjustment.

The dial indicator tower pivots for vertical and side-to-side positioning, and it accepts any standard dial indicator with a 0.375" mount, so you can use the gauge with your preferred indicator. The anodized base plate is rigid and stable enough to support precise measurements without drift or flex. Built from quality materials designed for a lifetime of use, this is a genuine measuring instrument, not a gimmick—the kind of tool you pull out when accuracy matters and guesswork won't cut it.
