I've been reading on spin drift. And I have a question I hope someone can answer. With spin drift being somewhere around 8-10 inches at 1000 yds. What is is going to be at 100,200,300 and so on? My way of thinking was that the instant the bullet leaves the barrel it begins its rotation to the right. Which means if I corrected my point of impact at say 200 yds, it puts my flight path back in line with the bullseye. Which I know from experience doesn't hold true. But at what point does a person need to begin to allow for the spin drift? Example- Do I not hold over until say 500 yds, then begin to compensate accordingly after that until I get to the 8-10 inch hold over at 1000? P.S- I am also aware of the 2.5-3 inch difference in point of impact the earths rotation has at 1000. Just so we don't get side tracted on the spin drift question.
