I use carbide dies for .357, .45 long colt, and .45ACP. While I know carbide dies do not require lube, I think a light lube might extend the life of the die.
I use a found-on-the-net formula of a small amount (1/2 tbls) of lanolin mixed in a 12oz. bottle of IsoHeet (red bottle), mixed in a spray bottle.
I line a food take-out tray with a paper towel and spray that with the lube mix. then I put the cases in the tray and shake it back and forth to lube the cases. It does make cycling the cases easier...
