It is nice to get a consistent COL and as stated measuring the tip to base is not going to do it for you. If shooting paper go crazy, if for the field, it needs to work in a magazine and that is the governing factor. You can get really wrapped around the axles trying to get the perfect round but the paddock is the great equaliser. Humans are more inaccurate than your rifle.

Hi..
I've similar problem with seating depth...seems related to pressure applied to press arm once it's come to a stop...on an old Lee press...
Using a Forster micro seating die...thinking a Cam over type press might eliminate this..
Using hornady comparator..variations up to 5 thou approx...
