Thread: When to re optimize seating depth ?

It sounds as if people aren't trying to extend the peak accuracy life of their barrels or chase drifting component specs to maintain max accuracy. Perhaps top performance has a shorter shelf life than that.

Recently I did recheck the case headspace, trim length and seating depths against what I had decided on 3 years (2000 rounds) ago and they had grown quite a bit. I guess my press has stretched or worn significantly. Or seating die.
