After being 99% sure I’d get an A22R pro varmint 22LR as my first rifle in 15 years, I end up coming home with a Lithgow LA101! Very happy with the rifle, however the new scope I acquired through the family is the Zerotech 4.5-18x40, I noticed right away that it was very very difficult to get a picture through the scope, it is extremely sensitive to head movements from the cheek weld. At a guess there is 10mm zone for eye relief and even more sensitive to horizontal and vertical movements, maybe 5mm! Then the picture goes black.
I tried 3 other scopes to compare, albeit with lesser zoom, they were far less sensitive to movements.
I briefly tried adjusting the focus on the zerotech, however I’m thinking now that I should have continued twiddling the dual.
