I purchased a CVA Kentucky pistol this week that had a good bit of rust in the bore, more than I thought at first. I soaked the bore in ballistol and later ran a patch down with the ramrod. All I can say is that there was a lot of rust in there and it held onto that patch like a South Georgia tick in your hide. The ramrod broke. I soaked the mess with penetrating oil and searched the forums. I came across a genius post by Husky about using a grease zerk and a grease gun to pump it out. NAPA hooked me up with 6mm x 1mm grease zerk fittings. Within five minutes, the problem was solved. I just wanted to say thank you for the post, Husky! At least one South Georgia boy sure appreciates it!
