Need suggestions for new scope for deer hunting

The bigger objective lens gives you a bigger exit pupil, but the human eye only works up to about 7mm, anything bigger is wasted, and a 50mm objective has an exit pupil of 7mm at about 7x, so any magnification lower than that WILL let more light through the scope, but it's not light your eye can make use of.

To believe that you have to believe that the exit pupil is of equal brightness across its diameter. It isn't, with the edges being duller than the center. Having the outside edges spilling over outside your pupil isn't wasting it, it's utilizing the best part. Sort of like cutting the crust off your bread. There's more; a large exit pupil helps the viewer get behind the scope. Marine binos typically have low power and large objectives. At first glance that would be seen as an adaption for low light but its biggest feature is the ability to use them from a tossing boat.

Few things are as simple as they first appear.

Interesting. I haven't heard that before, but it makes sense. I will have to do some messing around at low light with my 50mm scope and see if I can notice the difference in brightness between say 3x and 5 or 6x.

With any non fixed mag scope
You turn down the magnification down as the light diminishes
The clarity increases
 
Last week I made a shot 20 minutes after sundown at approximately 100yds into dark timber. The shot was a challenge, but I had no hesitation pulling the trigger. The scope was a Leupold VX3 1.25-5 with a 20mm objective. The German 4A reticle helped, but I'm confident I could have done it with a duplex.

Large objectives need high rings forcing you to lift your head off the stock. Good glass and the lowest possible mount for me.
