"Over stabilization" can result in trail -- the bullet continuing to point in the original direction of launch, instead of keeping it's axis parallel to the direction of motion. That's rare, and usually occurs at very steep angles, so the falling bullet hits the ground base-first (common in anti-aircraft useage.) Beyond that, it has no real effect on accuracy.
High velocity and a high rate of spin can initially over-stress the bullet as it takes the rifling, leading it to come apart in air from centrifugal force -- this used to be fairly common in very high velocity .22 centerfires
