It's very simple: call for the target with your eyes open. Focus on it, read its angle, and start moving the gun in time with the bird. Then, close both eyes as you start to pull the trigger. You'll crush the target. Once that becomes too easy, call for the bird and close both eyes a full second before you shoot. Stretch out, use your feelings - all that Jedi stuff - and you will be amazed at what you can do if you read the target's line and move the gun in sync with the clay.
