New Shoulder OD 0.400''

Fired Case OL 2.235''
Fired Neck Base OL 1.900''
Fired Shoulder OD 0.408''


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???
