In my looking for a new scope for my remington model 7 300 SAUM I find that there are more options in the 40mm. I kind of like the option of being able to mount it lower on the gun and the scope being more compact. But I was wondering what is the advantage of the 50mm over the 40mm.

The 50mm has little advantage over the 40, 42 or 44 mm`s........The 50`s are more money, higher profiles which don`t look as good, and somewhat heavier. There is perhaps a small difference in better light transmission from the larger objectives, but not enough to make a difference whether or not you fill your tags!!...............

Tell me if i am wrong but i would think a 40mm with a 30mm tube would bring in more light than a 50mm with a 1in tube. I would think only so much can get through no matter what you bring in. I would also think that the tube would be like a funnel the bigger it is the more you can get through at a time.

i would buy higher quality glass than worry about the size of the tubes and objectives, better glass cannot be substituted for no matter how big the tube or objectives are. a scope thats a 1" tube with 40mm objective would probably bring in more light than a cheapo scope with a 56mm objective.

Hi

 

the scope diameter has nothing to do with it's light transmission.

The innerdiameter in the scope when all the mechanics is counted of is betwen 7-12 mm.

I like big objectives, and if big objectives is combined with farily long scopes the mounting could sometimes be as low as a small objective.

 

Regards Technika

I am now contemplating between a Leupold 3-9x40 VX II or a 3-9x50 VX II. What is the advantage of the 50 over the 40.

Ability to use slightly higher power without exceeding exit pupil size. Very little difference however and mounting height - weight - and cost may outweigh this difference. I view 42 - 44mm as a very good compromise when available.....close to the best of both worlds.

I am an optics dummy what is the exit pupil size? Is that field of View? What about in low light situations? Such as hunting at dusk and dawn?
