Inherited a Marlin 60 in the box. Vintage 1960s-1970s semi-automatic. Pristine appearance, action was clean, lands and grooves cleaned well from Hoppe’s #9, performed well, but when I cleaned the magazine tube the rust was overwhelming the patch. Three or four runs with Hoppe’s cleaned it, but I’m wondering if I should use a different liquid than bore cleaner.
Any thoughts?
