so the resizing/shoulder push back isn't really a possibility
no it is not.
Could still be excess head space though. Put a piece of Scotch tape(or most any tape) on the back of a factory load and try to chamber it. You should not be able to close the bolt (or it will close hard). If you can chamber it with no problem then you likely have excess head space.
Your firing pin hits close enough to center.

Seems to me that you know a little more than I do. The only thing I can think of is headspace as someone else already mentioned.

hiwall,

I tried your suggestion and put one layer of electrical tape on a case head. Bolt closed easy and imprinted on about 1/2 of the tape. Tried a second layer of electrician's tape - bolt still closes easy, this time the imprint is all around. Tried two layers of masking tape - closes easy, can't see any obvious imprinting.

No offence, but are you sure this is a valid test? I've never seen anything like head separation or obvious stretching.....

No offense! Of course its NOT a valid test! But it is a very good indicator of excessive head space. At this point either buy a no-go head space gauge or take it to a smith that has one to get it checked. A no go gauge will be around $30 and works for many belted calibers.
