I listened to an interview with John Whidden (National 1000 yd champ in US) and one of his thoughts are to lube the case neck in order to get consistent case neck tension. I understand that this allows for the expander ball to move through the case mouth with the same level of friction, and hence get the same size case mouth. It is just another step, and it would be worthwhile to understand how many do this step and your thoughts?
