Winmagman,
I have used moly in the past and coated a lot of bullets until I learned of the undesirable effect it has on barrels the hard way.
Well, never again will I use moly!! To remove the moly I tried a lot of things and what worked for me was a can of "Brakleen" brake parts cleaner you can pick up in auto parts stores like NAPA or Schucks, get the red can.
When using Brakleen make sure to wear rubber gloves and please do it outside. the stuff is pretty potent!!
Lay your bullets on a rag,
Spray Brakleen liberally on the bullets, place another rag on top and roll the bullets around, should get most of the gunk off.
Then I tumble the bullets in a brass tumbler with corn cob media.
Hope this helps, it works for me..
