Archer58 hit it right on the head. Spin your arrows with the broadheads.Draw a dot on a wall, and spin them on the jig. Also be sure to spin the nock end as well. The nocks could be off just as easily. If either end wobbles outside the dot you'll notice it immediately. Mark any find, and set them aside. Then try shooting only the ones that spin perfectly. If all are ok, move onto the bow for errors.
