So the 42mm (if my math is good) gives about 10% more area. So should be gathering more light. But Has anyone proved to themselves that it performs better? Is the difference big enough to be noticeable by the average hunters eyes?
A comparable scope in quality to test would be the Leupold Fx3 6x42 against VX3 40mm set at 6x magnification. (I have the former but it can't really compare to my other 40mm which is a Leupold VX1. The FX3 is simply a much better scope.)
Curious if 1. anyone has done Such a test, or 2. people's general opinions on the two very closely related yet different objective sizes, or 3. Any history between the two numbers and how they remained in coexistence without one becoming the official "standard" objective size.
