Looking for advice. Got a Savage 6MMBR. On my 4th Barrel now. I have the Go, NoGo Gauges. Switched barrels here about 2 months ago. I have a 100 lot of new Lapua Brass. They have been loaded 7 times and I have 4 case head seperations ( not complete seperations,, just 3/4 around ejected fine). Every other time I have switched barrels I get about 18 loads out of the brass before I get split necks ( never case seperation). This is not a new barrel, just a older one that I put back on for the heck of it. My question is- When installing new barrel
A- Do you tighten till no go gauge does not close, but go gauge does
B- Same except keep tightening till go gauge closes, but just does. ( not with resistance though).
Right now I am tightening till no go just startes to not close, but go gauge does.
Is there ( Im sure) a area in there where just because no go does not close that it should still be tightened just a smidgen more. Hence making go gauge still close but tighter?. Should one go to were go gauge does not close and start backing off from there till it does?.
C- Did I just get one bad batch of Lapua Brass-Doubtfull but a possability.
Hope I explained this good enough.
I think what I am asking is- Just because no go gauge does not close , but go does, Is my headspace still to much and should be a few .000's tighter.
