Hello all, I am new here figured I would give my take on the cast bullet problem. Cast is all I shoot. Huntswithdogs, go to the grocery store and get you a choreboy copper pot scrubber pad cut a section off of it and wrap it around a brass brush for a tight fit a little Hoppes #9 or something like it and it should come right out. You fail to mention the caliber or dia. of the bullets. Shooting cast takes some figuring out what to do. But nothing like it when you figure out what you need to do. Also most commercial cast bullet lubes are useless in my opinion. I cast my own and make my own lube practically 0 leading. Hope this helps
