Hornady Lock-N-Load Ammunition Concentricity Gauge

The Hornady Lock-N-Load Concentricity Gauge is a reloading accessory for measuring and correcting bullet runout on loaded cartridges. Runout, the wobble of a bullet relative to the case axis, can come from several steps in the reloading process and can affect the consistency and accuracy of ammunition. The gauge is used by placing a loaded cartridge in the tool, rolling it, and reading the deviation on the dial indicator. The indicator then guides adjustment of the runout toward zero. It works with both reloaded and factory ammunition.

The gauge measures to an accuracy of .001 inch across a range of 0 to 1 inch. Its universal centers fit most bottleneck cartridges from 22 caliber to 45 caliber, with a maximum cartridge length of 4 inches. Precision adjustment knobs allow runout correction on each cartridge, and the sturdy frame can be bolted to a reloading bench. The housing is red.
