RE: Accuracy problems
Manually cocking the bow CAN cause the string to be uneven. I think AWshucks mentioned before to mark the string with whitteout on each side of the barrel before you cock it. Oncce at full draw check to see that tthe white marks as equal from the claw.
You might have something lose on your scope mount, possibly the base or the scope mounts or rings. Ther are infinite possible things that can be causing it. Did you try shootingone arrows then retrievingit and shootingit again, then the third time to see if each shot hits close to the priorshot>Might be you have a slightly bent arrow. The list can go on and on.
Put a regular crosshair rifle scope on it and try shooting, maybe you have a bad red dot. Could be you have a limb problem or cables or wheels.
You willl have to eliminate all the varibles to get to the root cause.
