So as I reloaded two rounds, forgetting to brush the case mouth with my graphite,  proceed to correct my mistake with the rest.
I can't believe the difference in the seating effort. ( forgot ). So having neck tension of 0.002" unlubed equal 0.002" lubed??

The dimensions will be the same but theoretically the "grip" will be different. It would be interesting to chronograph some of those round and compare velocities. The unlubed cases should develop a little more pressure and therefore have a slightly higher velocity.

If you remember when we started the polishing of necks and dry lube seating you do get aboit 12 fps faster speeds.
I still polish AND dry lube, seems to give me the most consistencey in es.
Hope this helps.

Polishing the inside of the necks? Please elaborate on your process and what are you using for dry lube and how are you applying it?

Yes that's what I think too. I need to borrow a Lab Radar and compare.
