I don't get too carried away measuring brass. If we see terrible es then start looking. For us, Peterson brass has made very consistent loads and able to push higher velocities than most other brass. Beyond full length sizing and chamfering case mouth I am not interested in brass prep. For current brass offerings, I think Peterson is as good as it gets.I haven't had the time to check out the dimensionally. I do know in the 500 280AI cases that the COAL was off between 50 cases that I did measure by .0065" between long and short. The reason for that is I cut the necks for thickness, and have to have the same or should have the same stopping point on the brass for concentricity. My thinking is fireforming would take care of the rest. Now volume case weight I haven't gotten that far yet. I figured that I would need to fireform them first, then measure for
