I'm not clear what you are asking. Clearly the ball is fully encompassing the missile and therefore everything is as it should be. It simply seems to me you misunderstand how to create a spherical reflection map, which has nothing to do with creating actual sphere geometry. It is merely an imaginary infinite sphere surrounding whatever object and as such only a texture effect, nothing more.
