This is correct.
My Sinclair uniformer mill for large rifle measures this, and so do pockets cut with it.
I have a K&M pocket cutter that measures the same.
The correct seating of primers is 2-5thou of CRUSH, and the only seater that provides for this accurately is the indicated K&M.
If you cut deeper with your Sinclair, and seat properly, they'll be below case head.
