Several schools of thought on this one, and it seems they've all been touched on in the thread.
My AR brass gets run through a regular sizing die with the expander button. Cases get Imperial Sizing wax, necks get Imperial dry neck lube (maybe every 4th or 5th case). Then they go for a 20-30 minute ride in corncob to get rid of the sizing wax.
Bolt gun brass gets run through a Redding Type S FL bushing die, without an expander. The bushings handle making the neck the exact size it should be, so those get imperial wax all the way up the outside. Then they, too, go for a ride in corncob.
If you are changing cases and powder is sticking to the inside of the neck, you're doing it wrong. Regardless WHAT lube you are using, you should be tumbling it off.
FWIW, I have friends that, instead of using dry neck lube, will just swipe a finger across the case mouth every 4th or 5th case (using Imperial wax) and that is enough to keep the expander ball happy.
YMMV.
