Thank you 'parashooter' for the additional information and explanations. I totally missed that the drift figures, in the tables you supplied, were caused and based on a 10 mph crosswind.

It is interesting that Hatcher states the 'gyroscopic drift' of the bullet to the Right, due to bullet rotation, is only about 6.7 inches at 1,000 yards (with .30-06/ M-2 bullet)
Maybe the Krag rifle initially sending a projectile to the Left, but, the bullet drifting to the Right and crossing the 'center line' at around the 1,000 yard mark, isn't a big deal and rather fortunate.

It appears good wind 'doping' is the critical factor at 1,000 yards.
