The Hornady Lock-N-Load Concentricity Gauge is the first tool on the market to both identify and eliminate runout. Runout can be caused by a number of different variables in the reloading process and can affect the accuracy. By identifying runout and eliminating it, your rounds become more consistent, which leads to better accuracy. Just place a cartridge in the tool, roll it, and identify runout on the dial. Once runout is identified the dial indicator is used to adjust runout to zero. This tool will work with both reloaded and factory to eliminate runout and make it a thing of the past.
