When shooting (recurve, rh) my arrows are far left of the sight, but i can't adjust any further left because it's at the end of the thread for the pin. And it's the longest one i could find. What could be wrong with the setup that would cause such a big drift to the left?
Without looking at you shoot or your setup, assuming that your recurve is properly set up and tuned, I would say that you are 'plucking' the string and pulling your hand out away from your face, with proper form, the string should leave the finger tab because the fingers are so relaxed they can no longer hold the weight and then your fingers should come back to the back of your neck. If this is done everytime; then it might help.
