From what I understand, "eye relief" is the maximum distance between the eye and the scope. Granted on high recoil rifle, it is good to have a large eye relief to keep your eye a safe distance from the scope.
However, what I don't understand is the measurement between the eye and the minimum distance from the scope where the full view can be seen. Once you establish a minimum distance, you can then take the difference between the minimum and maximum and this is the operating distance where the eye can be and still see the full view in the scope. Is there a name for this distance? Do scope manufacturers adress this?
It would seem to me that the greater this distance, the better the scope would be in a tactical situation i.e. you quickly raise the rifle to your shoulder and establish a shooting picture.
So I have ring around the collar? i.e. is my head up... Can anyone explain this to me?
