Reading in a past issue of AGW about adjusting the objective on a basic (Hawke reflex) scope for airgun use rather than centre fire use for which they are designed.
I thought i'd have a go:- so unscrewed the retaining ring and unscrewed the objective lens one full turn to bring it into focus at 10x mag.
at 40yds.
Then re zeroed the scope.
Now i knew the POI would have moved but not to the extent it had, 5" right and 2" high!
Is this normal?
