OK, here goes. I have a nice lyman push on or one that could be described as a barrel band ramp. I removed the set screw under the dovetail and oiled profusely with kroil. I tried to push it forward with a leather hammer and it will not move at all. There is some rust evident around the back section of the barrel. I would like to get this off so I could clean and polish the bbl and not damage the ramp. Any suggestions on how to safely remove the ramp without damaging it?. Thanks, Frank
