Haven't used my 21st Century concentricity gauge since I:
- switched to Lapua or Petersen brass
- removed the expander ball from all my resizing dies
- started using L.E. Wilson arbor seating dies
A few years ago Erik Cortina put out a video on his site on the subject of concentricity concluding you probably have bigger fish to fry on the path to accurate ammo.
