There's a video online somewhere that I now can't find. It showed a reticle moving against a grid the scope was pointing at ( the 'grid' was actually a brick wall) as the mag ring was turned
It was a pronounced shift from centre to left but the shift was gradual as the mag ring was turned. I don't know if there are varieties of movement, it's all to do with scope internal mechanicals, tolerances and assembly quality. There's a lot of stuff going on in a small space in a high mag variable scope, most of which I have no clue about. I just know the problem can
exist, in some
Give it a go, if yours does it, it's a relatively easy task to establish at what mag it happens, then don't mag above that.......or, don't change mag
I doubt it will though. Most are pretty good.
Here it is, it wasn't a brick wall, but a collimator grid https://drive.google.com/file/d/0B1w...w?pref=2&pli=1
