Spin drift is a constant, and can be accounted for in many ways. One would be to know what affect it has on your rifle at 1000 yards and go from there. In the distance the G7 will give out corrections (1400 max) I would not think many rifles would have more than .75 moa. and probably .5 moa at 1000 would cover most.
Coriolis effects are minimal out to 1400 yards. I usually do not include them in a soluton untill after 1200 to 1400 yards.
