How a Concentricity Gauge Improves Accuracy

Runout - a bullet sitting off the centerline of the case - throws shots and opens up groups. A concentricity gauge measures that runout on loaded rounds so you can sort your straightest ammo and diagnose which reloading step is introducing it.

Measuring Case Neck Wall Thickness & Runout

The NECO concentricity, wall-thickness and runout gauge (TM) reads neck wall-thickness variation - a leading cause of runout - while stainless digital calipers cover everyday case-neck and cartridge dimensions. Together they turn "feels good" into measured numbers.

Concentricity Gauge vs. Cartridge Alignment Tool

A gauge measures runout; the Cartridge Alignment Tool (CAT) measures and gently straightens it. Many handloaders use both, alongside other accuracy enhancement tools and careful case-neck prep.
