Despite popular belief, Gages are not perfect and no guarantee that my reload will match the new chamber. (Shop tolerance chart attached)
I would compare the radial dimensions a factory round to a reloaded round. Maybe the older brass has been shot in an overspec chamber ( maybe range pick up brass) and just developed memory that the dies cannot overcome.
