Biged that's what I was afraid of. When I set the cutter depth I measured spent primers and new, noted the differences, read all I could find on the forums, set my cutter depth at .131 based on what I could find as being the best recommendations, and when combined with the measurements I took seemed logical.
The biggest problem I have is with the bulk once fired Lake City 7.62 and 5.56 I buy. The military uses CCI #34 and #41 primers and the anvils are shorter. And a standard primer pocket uniformer removes more brass than with commercial cases.
Also every primer pocket uniformer I have is set at the factory for cutting depth, even the adjustable uniformers. Meaning I would never adjust the uniformer until after seating a primer and it was above flush. The first thing I do to check the uniformer is to make sure the uniformer removed the rounded corners of the primer pocket. This insures the primer cup is allowed to bottom out and put a preload on the anvil.
That being said I seated primer for well over 20 years without uniforming a primer pocket. And only do it now because I'm retired with nothing to do and all day to do it.
