Take 'em apart then soak the pieces in lacquer thinner, brush them out with big bore brushes, then rinse in that thinner again.
Blow 'em or wipe 'em dry.
Use Flitz on a rag wrapped on a bore brush in an electric drill, then run it in and out of your sizing die chambers. That'll smooth out the micro inch rough surface.
Clean them again the same way, they dry 'em.
Put a thin coat of rust preventing stuff on their outside, thin coat of sizing lube on the inside.
They'll now make sizing cases easier plus brighter and shinier than before.[/Quote]
