You could place them standing on a flat surface (tabletop), and see if they 'wiggle'. If they wiggle at all, you have high primers.
That really proves nothing. A properly seated primer is below flush with the case.
I looked at all rounds as I loaded, checked the primer to be flush on flat surface and they were, also checked each for oal-all o.k.--
The problem in this case is that the OP has completed rounds with high primers.
the depth of seat needs to be .004 below flush/case bottom?
the OP was questioning the advisability of reseating in a fully completed round.
