How far off are your broad heads from your field points? What have you done to tune your field points?
I would first suggest tuning your field points after tuning you should be able to shoot an arrow with no fletching and hit where you aim with with FIELDPOINTS at 15-20 yards. Once they are tuned perfect your broadheads should be very close.
Then if you need to adjust it will be fine tuning.
