Variations of ogive-to-touch (CBTO) across shooters come, not only from different chambers but all the different ID's of the tool we measure this with (Hornady or Redback). Hornady is not known for their quality control consistency of either headspace or ogive inserts. To be fair, consistency across inserts is non-issue if you use these things in the spirit of how they are intended to be used, by one person only. As soon as you want to compare across users that's when the differences in chambers and gauges render the data meaningless.
