Instinctive archery can be learned by anyone with enough practice. If I use aluminum arrows and shoot at a slower pace, I can keep 6" at 20 yards. Ran or shine, wind or no. I'm not as happy with it as you might think, I'd like to shoot 2". But it will/has get game. At what yardage are you happy with your groups? It just may be that you need to move up, and then slowly move back. Shoot one arrow. Draw and let down without shooting. Practice seeing very small spots. Always quit on a good hit. Visualize.
What AurthurP said is right on, only before you shoot with eyes closed, be sure to put the dog up! Poor rascal.<img src=icon_smile_evil.gif border=0 align=middle>
