Interesting to be reading this. After last year’s horrid hunting season, blaming myself, I decided to mount a reflex sight on my Vinci this season. I spent a very frustrating day at the range yesterday. Shooting various brands and sizes of shells through all the chokes I have and neither I nor my friend could get a centered pattern. Everything was high and left, and we ran out of adjustment range on the red dot sight. I am not blaming myself anymore.
