Bullets spin, which causes a slight tendency to drift horizontally over distance.
If you calculate out what speed the coriolis would require, you see that the idea of a balloon slowly floating upwards would be ludicrous under that condition -- it would be out of sight and miles away within a matter of tens of seconds.
You realize that if coriolis is real then landing a plane would be impossible?
