No need lube with carbide dies, lube if regular steel dies. adding lube for pistol case can add a lot of extra time to loading tons of pistol ammo
==================
In theory, you do not need to lube for carbide dies.
In actual practice, it just works so much better. Loading effort is greatly reduced.
When I started loading decades ago, I did not lube the 45 shells.
After a while I started to notice that my shells looked like belted magnum cases. They developed a ring around the bottom.
This was due to the pressure swaging the brass downwards every time I resized the shell.
The shells became shorter too. If it gets too bloated at the bottom, sometimes the slide would fail to go into battery.
As far as cleaning the ammo after loading, I suggest the carb or brake cleaner solution that I described in previous essays.
It is an elegant solution that leaves the shells clean, shiny and free of fingerprints. It only takes 30 to 60 seconds to clean hundreds.
