Hi all,
Before I tear my process apart, what is the expected concentricity I can achieve with this setup? Hornady L-N-L classic press, Redding micrometer seating die (upgraded from RCBS Comp). Using virgin Lapua .308 brass, and 175 SMK's.
My baseline is FGMM brass (fire formed), 175 SMK's, and RCBS Comp seating die. I was getting (out of 50), less than 10 at 0.001, most at 0.002 and 0.003, and 10 or so between 0.004-0.007. I'm using a Sinclair concentricity gage. My necks come out between 0.001 - 0.002 using a Lee Collet die.
Virgin Lapua brass neck concentricty is anywhere between 0.001 - 0.004. Other than inside/outside chamfer, I have not worked the brass. I reloaded 50 and most are coming in between 0.003-0.004 with a few at 0.002 and more than normal between 0.005-0.007.
Should I be concerned? I have 450 pieces of new brass to go, and would like to get the best out of my first loadings... any suggestions on changes to my process? Neck size them? Expander die? Anything else?
Thanks in advance.
