Please do not put words in my mouth or make assumptions. I collect British Enfield rifles and "NOTHING" supports the case rim but the forward edge of the chamber and the bolt face.

I also have headspace gauges for my Enfield rifles.

I can also measure headspace on my Enfield rifles using a set of feeler gauges placed between the reciever and right locking lug, or I can use a spent primer.

The feeler gauge is actually measuring head gap clearance and when added to the rim thickness gives you actual headspace.

I think I can say I understand the words headspace and head gap clearance.



And at times "excess headspace" is a pain in the backside and causes a foamy lip. ;D
