I have had that experience as well and found the problem to be primers that were not adequately seated. If I have a round that doesn't match my OAL-to-the-"ogive" I stand the round on the benchtop and found it rocks. I gently reseat the primer and the repeat measurement is where I expected it to be.
I got to where over the years I seldom have to stand a case on a flat surface to see if a primer is seated enough. In the beginning, I found a lot of them not quite deep enough even though they seem to be.
