[QUOTE="Gcan, post: 1701567, member: 102867"] Like I said, I’m not certain this is the place for this. The simple explanation is we are centering and plumbing our scopes to an action. That gives a vertical plane that is not on the same plane as the barrel. While the two x-y planes intersect at a theoretical zero (100 yards) they diverge from then on. The POA and POI grow increasingly further apart as distances increase. All I’m doing is setting the erector XY to the Barrel XY. Yes, movements are impossibly small. Yes spin drift is a factor, hence the fixture and movements in tenths. My scopes track 0/0 in the vertical. [/QUOTE]
