 God only knows. First, bore sighting is pretty crude, and as a practical matter you have to sight in at some distance. Bullet drop is normally discussed in terms of drop at a distance compared to a specified zero at another, fixed, distance. A hunter might wonder about drop at 300 yards with a zero at 150 yards, or a military man might zero for 300 and check drop at 600. Nobody ever measures from an exact parallel of barrel and sight plane, because that would be difficult and impractical to measure.Second, the velocity and ballistic coefficient of the specific bullet have to be known or at least taken into consideration.Third, you can only get an approximation from tables. To find out with your rifle, the only way to know is to shoot it and find out. There's just too much individual variation from one rifle to another, even two that are exactly the same in every respect that can possibly be controlled.
