Soy,when this happens to me,(arrows hitting left),I check 2 things first. (1),am I over-drawing, by pulling my drawing forearm past alignment of my arrow,and (2),how is my release. Am I getting a good hook,and, am I just relaxing my fingers,versus trying to snap them open,which in my case ,the string can hang on my fingers,and foul the shot. Think about these if it comes back to haunt you again. God bless
