This process is made easier with a simple accessory for dial calipers from Hornady. The 17-22 Rim Thickness Gauge eases sorting of .17 Mach 2, .22 Short, .22 Long and .22 Long Rifle rim thicknesses.

Hornady’s Lock-N-Load Concentricity Tool not only measures bullet misalignment on virtually any cartridge, but also corrects it.
