There is no reason to remove the lube, unless you are in the habit of dropping your round in the dirt. Lubed cases pick up dirt quite easily.
I got tired of 9mm cases bumping the powder out of my Dillion 550B. On station one the case to be sized (in a carbide die) went in so hard that the ram would bump the tool head. That caused powder spills.
So I lubed the cases and sizing was almost finger easy. It made a huge difference in lowering the sizing effort. And, I fired the brass lubed. Worked fine.
You see, friction between the case and chamber is undesirable, makes the mechanism run slow as the extractor has to yank the case off the chamber walls. Sometimes the extractor pulls the rim off, or simply comes off the rim. With lubed cases I was also able to reduce powder charges and the pistols/rifles still cycled. In my FAL, I was able to increase the amount of gas bleed off, which meant the action opened a little slower, and thus ejected the cases closer, with lubricated cases. Was much easier on the cases as they were not stretched during extraction.
Been lubing my 45 LC cases and leaving the lube on, I would have to go through ammo boxes, but I think basically all the long pistol cases I have been lubing the cases before running them through a carbide sizing die, and leaving the lube on, and firing them that way.
It is messier as you have to handle the cases to load, so, you can tumble off the lube on loaded rounds. Just don't tumble them long.
