Less blackout with 30mm vs 1" tube scope

[keen]

Question for those in the know with scope technical stuff...

I've got a basic Bushnell scope that I'm thinking of upgrading.

I've only really used 1" tubes in the past, no scopes with a 30mm tube. I've had a look out the door from my LGS, but that's not much of a test.

I don't know what the technical term is, so a crappy description is forthcoming...

Obviously when you move your head off-centre from a scope, you see the black edges. The further you're zoomed in, the quicker things black out...

Is this less of an issue with a 30mm tube? Is it easier to get a clear image and do you have to move further off-centre to start to see black or have it blackout?

Couldn't really say from a limited test in store, but by the time the lights been bent and magnified and whatever else, is there 'less' black in a 30mm tubed scope versus a 1" tubed scope?

Small gain? or just the same?

In my experience, no.

I have scopes with 1" and 30mm tubes and at the range there is no difference switching between them.

From a shooters POV the light is the same IMO.

Perhaps in some lab testing glass for light transmission or some other technical mumbo one is better than the other, but to a shooters eye I say no difference.

A quality 1" tubed scope will out perform a s**t 30mm tube scope any day of the week.

This is my experience too.

Larger scope tube is more about the additional windage and elevation adjustments that they can build into the bigger space.

Not about letting more light through.

+1.
grainweight is on the money.

Speaking of +1... What's with the no +1 here?

We toyed with member ranks and voting systems for a while...

While there is some merit to such systems, in the end they tend to cause more trouble than they're worth.

Regarding the original question of scope tubes...

You can get into all the technical mumbo you like to show which is "better". As said above, some machine somewhere probably gives the 30mm tube the green tick on this for some reason other than range of adjustment...

For practical purposes though, the only time you 'need' one is if you run out of drop/windage on your 1" scope.

How so?

How so?

As soon as there is a post count (some) people start posting rubbish to get their post count up.

You get hundreds of posts of "lol" or ":D" and nothing else.

Similarly for rank, people say controversial things and/or conduct ridiculous arguments all for the purpose of getting votes.

Someone with no posts or rank can just as easily post something very helpful as someone with many votes and much rank can post something completely useless or stupid.

In summary, a rank and voting system is not forthcoming
