I shoot 125 grain field points and 125 grain 3 blade Muzzys. My arrow, with BH GROUP slightly to the left of my FP. Notice I said GROUP. My bow is well-tuned and both FP's and BH's group closely, but at slightly different points of impact. Your problem is most likely a tuning issue and some good sites have already been offered. If your broadheads don't group with your fieldpoints, but DO group well, then adjust your sights for the BH since that's what you'll be using for hunting.
