Thanks for the clarification Hammerslagger.
I didn't think to discuss the cleanup of excess oils. My assumption was that all of us wipe excess oils at the end of the cleaning process. But, better to post it than to assume.
Your descriptions of the pressures on the breech face and the oil left behind in the pores of the steel make sense. I was trying to say that after some time of not being used and / or cleaned, the chamber becomes dry and needs a little help in releasing the case.
