The last Hoyt Raptor I tried to tune did the same thing.It was a bow issue and there was really not much that could be done to the bow.If it really bothers you that much,start playing with different spined arrows(than what the charts say),a lighter spined arrow might help.But whatever you do,maintain true centershot.Better to have a little tear and true center shot than to have bullet holes and and centershot off one way or the other.



Like others have stated,1/2" really isn't that big a deal(unless it gets worse as you move back)and it might be hand torque so try a few different grips to see what happens but don't get overly concerned.


I like paper tuning but you must really understand what can be going on and what is going on when doing it.
