My mandrels are nitride coated and I don't lube.
Good point here indicating a need for clarification in my post:
I lube my necks for 2 reasons, one more important than the other. First, I am protecting the TiN coating on my mandrels, but also lubing necks for consistent bullet seating pressure (and in theory, release). Neck lubing is a highly debated topic, with a specific nuance of the influence of brass cleaning method - dry tumbling tends to leave sufficient carbon and media residue in the neck to act as lube, whereas wet tumbling or ultrasonic cleaning cleans the brass too well and doesn’t leave any residual to act as lube.
