Hmm.. My experience with the AIM-9M is pretty good. I always take 1 when flying the F-15. And that one almost hits every time i shoot it. I always try to shoot it in between 2.5 and 1.4 miles. Make sure the target is not turning to sharp before firing and lead it. And if you are firing head on you have to make sure the closing rate of the target and you is not to high. If so you have to time the shot more early. But i always fire it against human pilots not AI.
