I talked to a starline tech. He said the reason its so stiff to seat is they have much tighter tolerances and should be different on 2nd fire. So I have to given them the benefit of the doubt. Nope. I don't ream anymore. Another tedious task I felt to not contribute anything so I dropped it. Might have helped here.

I have to admit. They are all 1.79" +/-.003 as guranteed case length. Never seen such clean square case mouths. Very impressive.
