Iduno, for 1st firing I care a lot less as i was not in control of the sizing process. Sd and es are basically never as good as after firing and resizing. Once fired from the intended chamber, then the attention to detail becomes hypercritical. I would rather have my case capacity established for my chamber than by factory dies and work from there. new brass I always just use as plinkers or sighters. Anything I care to establish reference groups, or compete with will be fired brass from that gun.
