Mineral spirits is the cheapest method, WD40 works as well, .... a nylon or bronze bore brush .45 gets the tough stuff, then a cleaning patch to dry 'em out....If I do them once a year, it's a lot. Generally, I only need to get the bullet lube out of my seating dies for cast bullet shooting. The jacketed stuff doesn't need it, nor do the sizing dies. If you need to clean the sizers, then you're probably using too much case lube. Rod
Our Flag does not fly because the wind blows against it,
It proudly waves because a soldier's dying breath blows upon it.
