I got a batch of once fired Win. 30+30 brass.When I checked them they had .010 neck runout.After sizeing in a new set of LEE RGB dies they were the same.I tried turning the case 180 in the sizing die and it didn't help.I loaded 12 and when I fired them runout is now .002,But when I resize it jumps to .005.Could it be I need to turn the case necks?What else could it be?Bad set of dies?My other LEE dies give me about .002 runout and I feel that is real good.thanks in advance for any help.I forgot to mention I also pulled out the expander ball and it was the same results.Thanks again.
