Just bought a Marlin 1894 Cowboy and its got lead in the bore close to the throat but enough that I want it gone.
I have not shot it yet but they must have at the factory.
I have used everything I have,Butches Bore Shine,Hoppe's,Shooters Choice,M-Pro 7 and wore out a good new bore brush and still some is left.
What are you guys using?
Thanks
