    I've had cases come out the rifle chamber like that after firing. No lube there. Different cause than in this case, no doubt.

    Probably gas coming back from thick neck/large neck clearance/low load not sealing neck against chamber.

    From what i gathered from opening post the cases were fine until sized.

    Yep, unless tight neck chamber turned cases and very small tolerance from neck to chamber that doesn't stretch the neck past point of no return.
