Ok I have a similar problem. My bow is tuned and shooting correct through paper. However my sight sits way out to the left of my string and arrow. I set it even with the string which makes sense for it to be that way. However I hit way left. What I realized is that because I shoot both eyes open and I am left I domanate and shooting right handed I'm going to be off a little to the left.

One thing to try is to close you left eye and shoot a while and see what happens. If that is hard for you to do then wear saftey glasses with the left eye covered like rifle shooters do. If this turnes out to be it you'll need to either buy a sight with more adjustment, learne to shoot with one eye closed and/or adjust your anchor, or switch to left handed.


Check your eye domanance. If you are left eye domanate your best bet in the long run is to switch to left handed.
