Perhaps I didn't make my problem clear. If there is an expected variance from one cartridge to another that's fine and I can live with it.
My real question/problem is if these variances are the result of my doing something wrong without knowing it.
I've read a lot about the precision with all this equipment. When I don't achieve the precision I understand I should be my first thought goes to "am I doing something wrong?"
I did open the jaws of my caliper .006". It is an amazingly small amount.
Maybe it's just me, but when I only focus on the numbers on the caliper I do lose perception of what that number really represents.
Thanks for the information - there'll be more questions to come I'm sure.
