your gun mount has to be consistent. if you mount the gun different each time, well its never going to hit the same place twice. then as mentioned above, put the gun on paper so your mind can visualize where the gun is hitting. also touched on above, gun fit. if the gun fits you, it will hit where you are looking, and it will hurt you much less. you can shoot well with a gun that doesnt fit, but it is so much easier if it does.
