Thread: Resizing inconsistency - Am I missing something

I've tried different lubes and techniques, and it seems to be par for the course. From what I've read if you anneal the cases correctly then they should all size the same.

With your 1.767 what was the measurement before sizing.

The only time I get a case discrepancy and it's always oversized is when I forget to clean inside my FLS die before starting. After each use I spray a shot of CRC Longlife into the die. CCR Longlife leaves a coating inside. This along with the lube on the case is enough to upset things but not to degree posted in this thread.
