RE: 3/4 inch groups ?
Do not get discouraged!!! I have been bow hunting for 10+ years now, and I need to fine tune not just my bow, but my shooting form. Here are a couple of things that might help. 1) Hold your follow thru on every shot. This is important because if you grab your bow after you shot, it may be throwing your arrows off. 2) Relax your bow hand. I hold my bow with little tension on my bow hand. I do not grip the bow until I shot and hold my follow thru. 3) Bend your elbow on your bow arm. When you hold your bow, if you are not already, bend your elbow slightly. This helps with the tension in you arm, as well as building up arm strength. I hopes this helps a little bit. I know you say you shot over 2,000 arrows, but I am here to tell you it will take more than that to develop the shooting form you are looking for. GOOD LUCK!!!
