It depends where the focal point is in the first or second part of the scope.
It's not masses out but once you go past a zero of 50 yards:
4x power gives my drops on the half and full mils at 50, 86, 113, 137, 160, 182, 202 etc
8x power gives the same at 50, 70, 86, 100, 113, 125, 137
10x power 50, 67, , 91, 102, 113, 123,
12x power 50, 64, 76, 86, 95, 104, 113,
As Sniper 101 says in his videos (the 75 i've sn so far) and from my own live testing and recording of info it makes a certain amount of difference
