[QUOTE="emp1953, post: 2167130, member: 71817"] Any time I develop a load with new/different components or change a component (brass, bullet) I do all the measurements, check concentricity/runout, and I write it all down. Then I chamber a few rounds and eject without firing and measure/check everything again and compare before and after. I occasionally find that the rifle's chamber fixes deviations I have in concentricity/runout. My old RCBS press had started to wear, I could wobble the ram a little bit and the 30 cal shell holder seemed to allow the case to "not be straight" as it entered the die. I replaced the press with another RCBS and all the weird measurements went away. I always checked my reloads in a Lyman Ammo Checker go-no-go block. Anyway, before and after the new press all my ammo shot to "minute of deer" at 600yds. This echoes what others are saying here that all the measurements that deviate from perfect sometimes don't make a hill of beans difference down range. [/QUOTE]
