I shot some loads through my 870 barrel, probably left the cleaning too long
now there is a ring of what appears to be pitting in there about half way up the barrel, I don't know for certain if it's just leading, I fired about 50 rounds of winchester, remington and some challenger slugs through it. I have heard the Challenger slugs use cheddite primers which I heard were corrosive. Should I try to hone the bore to get rid of it if it's indeed pitting.
