My BH and FP do not have the same point of impact,yet both group well w/ each other. We've tried tuning the bow but no luck. My buddy who helps me with this has an older bow that is just like mine, his switchback however shoots them both the same. Some older bows just won't have the same Point of impact when shooting BH and FP. I sight in my BH and practice w/ them for a month before hunting season. All summer I use the FP,way easier on the targets!
