There already us ammo with builtin microprocessors for adjusting trajectory etc. This coupled with some kind of guidance computer, communication with the gun sights etc would solve all kinds of problems. The sights could "project" on a screen where a bullet will land, for instance, taking into account all sorts of data, for instance where the previous shot ended up.
