[QUOTE="eshorebwhntr, post: 1155551, member: 17112"] Better glass will trump bigger bells on scopes any day. However, light transmission in scopes does have something to do with the obj diameter. The human eye pupil can dialate to about 4.2mm in low light. When light passes through any glass the transmitted light will come through in a ratio of Obj diam/pwr. That is why the 10x42 binos are so popular 42mm/10x=4.2mm. So the bino's are chunking as much light through as your eye can take. So for your case consider your furthest shot at last light, what power on your scope you feel comfortable shooting that far with, and then size the bell on your scope accordingly if need be. I'd say for shotgun range you'd be 200 or less which with practice you could accomplish with 3-4 power easily so any scope on the market should work. A little long winded I know. Just thought someone out there might like to know how all that works. [/QUOTE]
