RE: Accuracy and shooting tips....
Another good thing to practice is aiming,ONLY.
Pull your bow back,anchor and get set just like you are going to shoot and just practice holding the pin,or letting it float in the middle,then let down.Try it at 20 yards and then about every 5th arrow or so,let the release fire.You will be amazed at the accuracy you can achieve doing this.
Also,getting a back tension release could be a huge help in teaching you a proper release and teaching you what it feels like.
Trying to get your form locked in is also crucial.You need to find out what good form is and start trying to achieve it.You will find slight variations that will work for you but learning a good base is crucial.
