Question for those who removed expander from FL sizing and use Mandrel

[JFrank]

I spoke to Redding today about this very topic as I have 2 new builds that won't bump after the first firing. They said if it does not bump and still chambers then you are in the best possible spot. They also said at some point expect the brass to stretch enough to where it does bump.

This is what Richard Coody has mentioned several times in his posts regarding brass that hasn’t been fully fire formed yet.
