Re: 44 vs 50mm?
One factor to consider is cheek weld ie the distance to your eye above where you comfortably cheek the Stock . The Scope Objective ACTUAL Diameter , Base & Rings will dictate this . As far as light gathering , one Brand 50 may or may not be brighter than another Brands 44 ...... Number of elements , type of glass & coatings , etc . Then you can consider the various tube Diameters and Brands , etc . to determine if you are happy with Vertical adjustment Range . Then there's the Macho factor of the 50s which I think sells some Scopes ..... the bigger is better syndrome .
