I've been researching this quite a bit, and it doesn't take long to find out that a 1" tube will pass all the light your eye can use. Several "hands on" test have shown that a 1" is just as bright as a 30mm.

I have a 4x Zeiss on another rifle, and i use to sell Zeiss long ago, so i'm aware of there quality too.

What i "thought" i wanted when i started looking is an 8x scope about 50 or 60mm, but maybe that isn't what i'll end up with after all, as the variables are much better these days than they "use to be".
