beaver#1,
How long is your draw and how long are your arrows? Your arrows could be weak spined with those points. What are you seeing relative to arrow flight? Are you saying the flight is inconsistant and the arrows are all over, or are they always low and left, high and right, etc? More info will help nail down your problem.
As to "aiming" ... perhaps you should start very close to the target, like 10 yards or so. As you draw, give a good hard focus on your target, hit anchor and release. As your "aim" improves, step back 5 yards and get good from there. Shooting instinctive has little to do with aiming and a lot to do with a good hard focus.
Anyway, I am no expert. You will get info form others, shooters much more skilled than myself.
Good luck to you.
Bob.
