Different strokes for different folks. BR world is different here. This is what Calvin is alluding to above.
Not too many guys running more than about 50 firings in the PPC cases anymore. I throw mine out after about 20-25 firings, usually due to work hardening. Surprisingly the pockets aren't the issue.
There was a time in BR when you couldn't get PPC cases all that readily and shooters had worked out a way to stretch cases to about 250 firings, myself included. BR is no longer about preserving brass life forever. Too many problems with work hardening and inconsistent neck tension etc. Those days are long gone. Hard to win today using the low pressure loads and work hardened brass of yesteryear. Today it is redline plus.
Fresh brass provides a noticeable improvement in gun handling and speed as the force required to chamber and extract it is so much less. No amount of custom dies (bump, fl, bump and squeeze etc), will remedy brass that has passed its prime and no longer responds to the dies. And annealing is in no solution here due to the inconsistent nature of the process. Just get new brass!
Jesus, thank god I didn't get hooked on BR shooting. At the price of Lapua brass these days I couldn't afford to be throwing brass in the garbage that often.
