Are you shooting your broadheads through paper or are they just impacting left of your field tips. I think i read that your shooting them through paper and you shouldnt. You paper tune field tips and then move to a broad head target. Shoot a broad head and then a field tip. If your lucky and bow tuned correctly they will impact close to each other. If not you make adjustments (very small) to the rest and nock point to get the broad head impact the same as field tips.
