When working the trigger, “Curl” it rather that “press” or “squeeze” it. Most people have more control over the amount of pressure being applied to the trigger when they feel the finger being contracted in a curling motion around it. When a finger is suspended on the trigger face, when using a press or squeeze technique, you will not feel that controlled sense of contraction required when releasing the shot. (It must be noted the finger position on the trigger will affect the quality of the shot, so make sure as you curl, the pressure is straight back.)
