Besides the trajectory, or curved path, you have to allow for the drift of the bullet. This drift of the bullet is caused by the rapid rotation that the rifling of the barrel gives it; in a rifle with a right-hand twist the bullet spins rapidly to the right and when shot over long ranges it moves to the right, and this is caused by the bullet rolling itself over in the air.
In some rifles there is a slight side wise jump to the left, and the way to find the total horizontal deviation of the bullet without taking windage into consideration is to subtract the amount of the jump from the amount of the drift.
