I got a new Bow tec destroyer 340 and was having arrow flight issues at the bow shop. We paper tuned it at 10 yards and thought we had the problem solved brought it home and started to shot it at 20 to 40 yards and still having erratic arrow flight. Arrow cork screws to the target then the tail of the arrow goes to the right the straighens up and hits target. I'm shooting 60 lbs at 30 1/2 inches with a ultra rest LD and carbon express maxima hunter in a 350 with 2 inch fusion vanes with a slight helical. Can anybody give any suggestions on what the problem might be and how to fix it.
