Case gauge time.
Spent a few minutes re-measuring a sample of the 9mm I made last week with both calipers. There was a consistent .005 difference in digital vs the dial, with the dial measuring shorter than the digital. The dial was bought from Craigslist, I asked when it was last calibrated. The short answer I received was, "a month or so ago by the shop's weights and measures guy". Good news is that the there was exact consistency in the readings, which I went through and did twice for 5 different cartridges.
Bad news is that I don't currently own a gauge block so that is next on the list to pick up as soon as possible. If anyone has a reason that I should look for something more that what I found at the Home Depot site, please let me know.
