I have a 12 gauge 870 I'm going to polish what size should the scotchbrite be cut to fit on the 20 gauge bore brush? I mean should it just fit brush and ends meet or should I overlap the scotchbrite. I know I could just cut random pieces but I'm not one of those people I prefer measured repeatable results. Anybody have a size measurement they use for the 12 gauge 870 Thanks
I cut mine to meet in the middle.
