OK here's the question and it may be a bit long/complicated: All others thing being equal, and using a 0 MOA base for a .308 Win, will the POA/POI shift between 100 and 200 yds be different? if so, which way? Will this difference be magnified using a 20 MOA base? @ 100 yds, the POA and POI are the same, will the POI be higher, lower, or the same at 200 yds? how will the difference be magnified using a 20 MOA base?
