Fired and Unfired Brass--any correlation?

Un Fired Brass = Too Small

Brass Fired in My Chamber = Just Right :-) JMAO

Thanks, FW. I had read about this method, but it finally sunk in when my new 22-250 was growing my new Lapua brass excessively. I finally switched out the factory barrel for a match chambered 8 twist and deliberately set the headspace to minimum when installing the barrel.

I should mention here that I am shooting a bolt gun, not a semi-auto, and there is a difference in procedures between the two.

Now the shot brass measures almost exactly the same, shot to shot. I neck size only and check chamber fit as part of my cleanup procedure. If it fits, I don't need to bump the shoulder. I am using Lee dies (four die set) and am seeing great longevity in my brass life.
