Cartridge Alignment Tool (CAT)

How the CAT Measures & Corrects Runout

The CAT indexes a loaded round and reads bullet runout, then lets you nudge the bullet back toward the case centerline - measuring and correcting in one tool. Straighter ammo chambers better and shoots more consistently.

CAT vs. Concentricity Gauge: Which Do You Need?

A concentricity gauge tells you how much runout you have; the CAT lets you fix it. Serious loaders end up owning both - the gauge for sorting, the CAT for correcting - plus other accuracy enhancement tools. Designing a wildcat? See QuickDESIGN.
