Ray, you need to go one more step to make your measuring complete.
FL resize the cases "normally" (jamming them as far into the size die - with and/or without an expander - as a shell holder will permit) and check the case length again. I think you will find the "neck" stretch you are looking for then.


Jim, I missed your post the first time - Just saw it.

I don't see how this could have anything to do with resizing???

The "New" case was measured after resizing and the "Fired" case was measured before resizing again???
