shoot some paper and see if you puncture or rip.
follow through....
Not your sights! Arrow has some side deflection (i.e., need to move rest to find center shot). So, as Bone recommends, you need to shoot some paper. Sounds like your rest is a little off of center shot. Start w/FPs. Again, you need to shoot a bullet hole thru paper w/FP's FYI, if you are shooting left, need to move rest slightly to right. But, first make sure there is no contact of fletches with rest before you try to tune center shot.
