It is on once and twice fired brass that I noticed. I figured I wouldn't worry about neck turning if the difference is 1 thou or less but in some cases it's 2 thou
Peterson. All my measurements virgin are awesome. Usually only 0.0005 thickness variation and maybe 30% about 0.001
Yup. Imperial dry lube prior to expanding.
I've got some more virgin brass so I'll have to take some more measurements throughout and pay closer attention

What is your fired neck diameter vs your loaded round diameter?
Loaded is usually 0.3375 and fired is 0.341-0.342 depending on anneal
One other question. I talked to someone at Manson a couple weeks ago about a reamer and the prints they sent me that they had on file.
Most 30-284 reamer prints I've seen have the head diameter that is 0.200 from the base being 0.501. My dies size my fired brass down to 0.4995-0.500 at that point. To avoid an eventual clicker problem like what the 300 prc has going on, do you think I ought to have this dimension enlarged to 0.502 or 0.503 to avoid it? I plan on taking this brass to as many firings as possible, so I think it's possible I'll eventually have brass that's too hard in that area to size it below 0.501. virgin measures 0.499.

My gunsmith rented the .30 Gibbs reamer from 4D without any issues.
