POI change between mags????

"addertooth"Most importantly, what model and year of production was your scope?
Not sure what the scope has to do with it? Sounds like its a predictable poi shift between a couple mags so to me that would have nothing to do with a scope.

Did you alternate which mag you used first? Does each mag have a consistent poi no matter which is put in first or second? What I am getting at is the possibility the poi change isnt the mag but the pressure change at the point the mag gets changed.
