I cleaned the rust out. It resulted from the Chiappa being testfired at the factory and then not cleaned, as the manual advises for this very reason. Unfortunately the rust has been in the bore long enough to do it's damage. The entire bore is pitted. This barrel is junk. This shows you what really happens when you don't clean your steel gun-barrel. It doesnt happen overnight. But it doesnt take long.
