Dan,

If your comment were true, we would not need resizing dies. Afterall, if the brass "springs" back it would not be oversized.

The truth is that the thin wall sections of your brass cartridges are stressed to 100,000+ psi during firing. Since the yield strength is around 35,000 to 65,000 psi the thin sections of the brass case are plastically deformed. Hence the need to resize your fired brass cases.

I know how much the extraction effort increases with cartridge size increases in a given action/barrel shank combination. I was interested in seeing if anyone else had something to contribute.

I don't think you will get a mauser style action to extract a 600 NE that was fired off at 50,000 psi without a SIGNIFICANT effort.

What is the receiver ring diameter, and barrel shank diameter for your Heym 600 NE?

Regards,
Scott

Aw, come on, Scott, enlighten us. Back when, when you were Axel (and still are, I'm sure) you were an engineer/rocket scientist. You ought to be able to figure it out in your head.
