@BombSlayer123 - Because bullets are smaller and usually have higher densities than meteors and they have a much higher initial velocity and, they are aerodynamic and doesn't have much wind resistance compared to a meteor.
The only thing that bugs me is that the characters cannot be moved between the slots in the Character Choosing dialog where you choose the characters for a mission.
