My math skills are corroded by time, but just thinking about it, shooting east/west and vice versa, the rifle, bullet and target are all traveling in the same frame, Applying Newton’s theorums I’m not seeing how the trajectory would be affected.
Shooting north or south, coriolis effect would apply but would be greater over the equator compared to standing on one of the poles. The speed of rotation at the equator is faster than it would be either 1000 meters north or south but the variation would be small and it would take me hours to remember the math to calculate the difference.

The target is moving up/down relative to when you pull the trigger.
