Mike,If after neck turning both lots weigh fairly close to each other (within 1gr) I'm betting there is no need to Aztec another. There isn't a whole lot of temperature variance between 1-2 Aztec 'codes'.
I don't shoot 6BR, but if I were in the same situation, weight variance would be my deciding factor.
Thank you sir!If you look at the Standard mode in the AMP settings table and then scroll to 308 or 6BR etc and then find all the Lapua brass tested you can see the variations you are likely to get.
