Is it always the wrong heading by the same amount?
That is if you want a heading of "up" and the bullet is heading "left", and then when you want a heading of "Right" the bullet is heading "up".
Is so then there is simply a transform addition/subtraction missing from the angle. Add a constant to the bullet heading. (Try 90 degrees or pi/2)
