40's are most all you will need. They are easier to mount on a rifle and see through as you don't have to go high with your cheek on the stock. That being said the 50mm will allow more light and give a slightly wider field of view.
Something to consider also is tube diameter. A 30mm tube with a 40-44mm obj. will allow more light in than a 1" with a 50mm obj. Of course quality of optics will make a big difference there.
Lens coatings make the most difference though. You will get more light in a 40mm new scope than you will with a 50mm older scope.

Well you will get a lot of opinions on this one that will be conflicting, so here's mine based on my experiences. I own primarily Leupold scopes on my hunting rifles my .338 has a 3-9x50 Vari-X II on it and for the life of me I can't find any difference between it and my other rifles that sport 3-9x40 Vari-X II's. I see no discernable difference in low light conditions, both scopes perform very well right up to the last minute of ethical shooting. On my rifles that have 40mm objectives on them I am able to use low mounts, on the 50mm you have to go to higher mounts and on some guns and with some shooters this brings your face up somewhat so that you may not have a tight fit between your face and the stock. This combo may make for either uncomfortable or innaccurate shooting for some people. I personnaly am not going to spend the higher amount for a 50mm when I can have a 40mm that performs equal to a 50mm.
Please keep in mind this is just based on my hunting and shooting experiences, some other peoples opinions may vary!

I have a scope with a 56mm objective, given to me by a friend from Sweden, where night hunting for some things is legal. It sits so high on a rifle (yeah, I tried it for a while) that I loose my cheek weld to the stock. Whatever extra light it transmits in daylight is wasted on a huge exit pupil when my own pupil cannot take it all in. It makes very little (I cannot detect any) difference over a 40-42mm objective at twilight. It could be used at night only with artificial light.
If you frequently hunt in very low light situations, you would be much better served by high quality scope with an objective of 40 or 42mm transmitting 90+ percent of available light, than a lower quality scope of with an objective of 50mm or larger. The large objectives must be mounted high and you loose consistency in your shooting. If a vari-x III in 40mm does not transmit enough light Leupold does make a scope they claim transmits 96% of available light. In the US I see little if any reason to use a scope of 50mm or more unless perhaps for varmit shooting at high magnification.0 -
Thanks for the responses. Question answered.
