I suspect the arrow spineis too stiff for the 60# bow. It may be slightly stiff for the 70# bow and then, when you try and shoot it out of the 60#, the stiff spinebecomes abig problem, as you can see.
I agree! Stiff arrow spine can cause that type of a problem. Is the bow walk back tuned? Are the arrows from 20 to 50 yards all flying in the same vertical plane?
Hope you get it worked out! I had 2-08 82nds and both tuned right down the middle
