I put 80 rnds through it last weekend and cleaned it very heavily. I cleaned it once, when I got back and then just a follow up that night. Each time I would run a brush and patches with some Hoppes 9 to where they were coming out clean. Yet after waiting a couple of hours, running a patch through reveals all the green blue residue from the copper. It doesn't seem to ever come out. Is this normal? Will it ruin my Mosin? and how do I get it out?
