Depends on the case length if I use lube or not, even with carbide dies. 45 ACP and .380 I do not lube and use the carbide dies as they are. .357 and 45 Colt I twist the case neck lightly and coat the last 1/16" of the case with lube. .357's almost disappear effort wise and the 45 Colts are so much easier to size. It is worth the time it takes to remove the lube with a damp paper towel.
