Ok, then I don’t have a problem … never mind.To measure for pressure your measuring at the web just ahead of the extractor groove. Even a small base die doesn’t size that far.

IIRC this pressure measurement method only applies to subsequent firings....after the first firing.If this is true, then none of us should be reloading. There should be no such thing as a small base die. We should all trash our brass after the first firing.
OK, LETS HEAR IT

Hey Tom,Not to beat a dead horse, my thought is you will be catching an over pressure load almost immediately, before the primer pockets loosens, saving your brass & preventing premature failure. Your not looking and you won’t get pressure numbers for your load you just looking to stay below excessive pressure or .0005 growth in the said area.

I reread your post several times and I think the answer is yes you are correct in your thinking.Not to beat a dead horse, my thought is you will be catching an over pressure load almost immediately, before the primer pockets loosens, saving your brass & preventing premature failure.

on the cases with signs of separation did you have a heavy bolt lift? It could be you were bumping the shoulders too much if you don't get a heavy bolt lift.I measured up the cases again with a caliper and headspace comparator
My bump is between 2-3 thou inch
Interesting thing I noticed that the cases with signs of separation, measured 2 thou longer than my fired brass
