The book tells me that I should set the die 1/2 turn back from the point at which the die contacts the case holder when the press is at its highest point. Then test the round in the rifle and it should chamber easily at some point.

I backed the die of 1/2 turn and it seated just fine. Should I back off the die until I find the point at which the case will no longer seat in the action?

Can I re-run the cases that I've already run back through the press? Will running them through again decrease the case life?
