Yeah. I worry about that about as much as I worry about the bullet’s rotation. I’ve heard things about the Coriolis Effect, too.
If you are shooting at great distances, you must take many variables into effect. The Coriolis Effect is due to the spinning bullet and thus the twist rate and direction of twist of the barrel must be taken into account. SO you have bullet velocity, crosswind velocity, ballistic coefficient of the bullet, twist rate and direction, temperature, humidity, the rotation of the earth under the path of the bullet, among other variables to deal with.
