nice if figured it out this is the way i was thinking.
how i did it was i made a new bone for the bullet. that wasent connected to the gun handle so if i turned the gun the bullet would stay in mid air. then i made a on/off pose of the bullet bone constrained to the handle. so to animate all i have to do is put the pose on. point the gun. go next frame force keyframe turn pose off. then go a couple of frames further and set the bullet movment pose how far i want it.
it sounds more counfusing and harder than it really is.
