Using the RCBS Concentricity Gauge I find that some of my 30-06 cases are showing the initial signs of head separation. By this I mean the dial indicator bounces over the likely spot for separation showing about .002 +/- thinning of the wall thickness. Does this indicate that it is time to trash these cases or is there a little remaining life in the case? How much thinning becomes significant?
I am loading near max loads, 56.0 gr H4350 and 61.0 gr of Reloder 22 for Nosler 180 gr Partition and Accubonds.
After sizing my cases I check neck concentricity and find most are .002 or less run out. After using a RCBS Competition Seater Die in my old Lyman Spartan press I check concentricity of the bullets, again Nosler 180 Partitions, and find .005 to .007 run out. Using the Hornady seater die in a New Dimension Die Set that I picked up used at my LGS the results are .005 run out with the same load.
Can anyone point me to a solution to reduce the run out of my finished loads? Thank you in advance. Rol
