I have a Marlin 1889 chambered for 32/20. I have been using a light load of Unique with reasonable success. I want to put together some black powder loads for the gun just for grins. When I shoot the holy black in single shots and muzzle loaders I run a patch or two down the bore frequently, usually after each shot. Not to practical with the lever repeater. How do you keep fouling under control in one of these guns?
