I have had a badly fouled/ rusted 45 barrel made useable by lapping it with silica flour which is sort of valve grinding paste. It was done with a wool mop covered in a paste of this and light oil and about 100 passes through the barrel.
The stuff coming out was a horrible dark brown but when finished there was white metal, and you could see the rifling and the pitting.
Shot fine for a black powder cast bullet rifle.
