rd, here a couple of pics/illustrations that show what the gage measures.
Head space is the distance from a datum in the chamber to the breech face. In this instance it is the distance from the cartridge shoulder to the breech face of the Contender pistol. If you have too much head space or "slop" the cartridges can stretch excessively or even worse they may fail to fire.
I'm afraid you've lost me.
The .218 bee is a rimmed cartridge. But you saying you are resizing your cases based on the cartridge 'shoulder' up by the neck of the case? Or by 'shoulder' do you mean the barrel counter bore? I'm not sure which one you are referring to.
If you have excessive head space, either the rim counter bore is too deep in the barrel or the barrel pivot pin / lug hole / frame holes are worn allowing the barrel to move forward. I don't understand how you could resize your cases (making them longer) without leaving a portion of the cartridge case ahead of the cartridge rim unsupported, and subject to separation.
Color me confused.
