Hornady Lock-N-Load Concentricity Gauge 22-45 Cal Red Multi-Caliber

The Hornady Lock-N-Load Concentricity Gauge (050076) is a precision reloading tool designed to identify and eliminate bullet runout (wobble) in bottleneck cartridges from 22 caliber up through 45 caliber. Whether you are loading match-grade handloads or just want to clean up factory ammunition, this concentricity gauge helps reloaders squeeze extra accuracy by truing up bullet-to-case alignment.

The Lock-N-Load design uses universal centers that hold the case at the base while a sliding indicator measures runout along the bullet. Easy-to-use precision adjustment knobs let you true up runout on any bottleneck cartridge, and the gauge ships with three interchangeable mandrels of varying sizes to cover the most common bottleneck case mouth diameters. The red finished body sits on a sturdy cast iron base that stays put on the bench while you work.

This concentricity tool is just as useful for QA-ing factory ammunition as it is for handloaded rounds. By measuring runout and indicating which side of the bullet needs to be re-aligned, it is a fast, repeatable step that pays off in tighter groups downrange.
