This is getting very complex Mr.Guffey. When I asked you to correct me if you see fit. I was wrong to assume you would give a better description of how the head spacing stretches the case in detail of the firing of the round. Not how your heavy firing pin doesn't cause case separation. Here we go again.

Correct me if I'm wrong. But don't get off track. I get confused easy.

If the case is FL sized to a length less than the distance from the bolt when closed too the chamber shoulder or is it datum? "In a 308" The case is expanded do to the pressure of the powder charge in all directions. It's stretched out to the chamber walls, back to the bolt face and forward to the chamber shoulder that acts as a gas check and the neck to the chamber neck walls. So if you resize the case to a shorter length. It will stretch to a longer length. That is what causes (Metal God) to give us a fine picture for reference.
