I have always looked at the process steps required to prep brass. The order of those steps, in my opinion can influence the outcome.
Take for instance Dasher fireforming. Cases fail at the shoulder occasionally. Those failures can be dangerous due to escaping gasses.
These two cases show what would have been two case failures. I have not fired all of the remaining cases (about 300 total) to see if I'll have any more failures, but the order of operations saved me from two bad experiences. Both of these opened up during annealing.
So, my current order is:
Skim turn necks
Expand to .257
Anneal (aimed at the shoulder)
Neck size to .266
Load and shoot - 30.5 Varget .007 into the lands
