Head on the gun! Eye on the target! Just get out in front and pull the trigger! Its not presice target shooting, its friggin handgranades!
When people say they shot behind the bird, most of the time is because they took their eye off of it for a second to look back at the barrel to check their lead. Then they pulled the trigger and missed behind the bird. When you take your eye off the target, your gun stops. Making you miss the bird in the back. Happens every night at the skeet field. By increasing your lead your not fixing the problem, your just crutching it. Keep your eye on the target. your gun will get to the right spot with hand eye cordination and a lot of practice. my .02 anyway!
.....you've got to ask yourself a question: 'Do I feel lucky?' Well, do ya, punk?
