I was given a rifle from a friend of mine. He gave it to me because he claimed it was "junk." He had used it during deer season then put the rifle in his basement for many months, uncleaned. He did not want to try to save the rifle so he gave it to me. Looking at the rifle you would have throught it was a lost cause. Although it did have some parts off it I could use.

I took the rifle and spent days cleaning it the conventional ways. It was a mess. The outside of the barrel was rusted. The inside was rusted. So I figured I had nothing to loose and lapped the barrel. I did not get all the pits out of the barrel but at least the rust is out. The rifle by the way is a real good shooter. With roundball and 70 grains it is an exceptionally accurate rifle. A pitted bore is not the end of the world...

Just don't do it on purpose. Get some oil down them barrels...
