For the most part, hunting rifles wear glass nowadays.
And, most rifles seem to be tapped straight and CNC manufacturing seems to produce some excellent rings.
Its not outside the realm of possibilities for a person to be able to mount a scope and zero it for hunting distance within 10-15 clicks either way of center.
So, what advantage, if any, does a modern 30mm have over the same objective diameter 1" tube scope? Equal power and quality of glass assumed.

On paper the 30mm tube that has the same wall thickness as a 1" tube will be 'stronger.' I have no idea if this would benefit any one in the real world...

So, what advantage, if any, does a modern 30mm have over the same objective diameter 1" tube scope? Equal power and quality of glass assumed. I'm with you. A 30mm scope seems to have a big disadvantage. It prevents switching scopes without switching rings, too. I've heard 30mm is a standard for European scopes. I don't know whether that's true or not, but I see a lot of Euro scopes with 1" tubes. On the theory that a 30mm is stronger than a 1" tube of the same thickness, I have my doubts. If that were true, wouldn't a 4-foot pipe with the same thickness of a 1" pipe be stronger than the 1-incher? Another disadvantage is that the 30mm is heavier. Steve.

All the inbreds down here will tell you with 100% certainty that they "gather way more light."

bloodworks,
Everyone knows that. Did you know any reason for a 34mm?

If I asked a random inbred they'd say it's essentially night vision.

One advantage to the 30mm tube is that you can fit more stuff in there making 6x and even 8x zoom ranges possible (Swarovski Z6, Leupold VX6, etc.) so instead of a 3-9, you get a 3-18.
There can theoretically be an optical advantage if the manufacturer uses 30mm internals because a larger lens is easier to make correctly and is more efficient. Having said that, most 30mm tubes have 1" internals to provide more range of adjustment.

kilmer,
Speaking of Swarovski and Leupold.....
Today I compared the Swarovski z5 5-25X52 (1") with a Leupold VX-6 4-24X52 (34mm) on deer antlers 131 yards away in the woods and 127 yards away on an "eye chart".
It was about 1:45 with an overcast sky. I adjusted the side focus and magnification as best I could and still see a particular point on an antler.
VX-6 - 8X
z5 - 9X
bottom line on "eye chart"
VX-6 - 17 1/2X
z5 - 18 1/4X

Steve. A 4' pipe of the same wall thickness is undoubtedly stronger (will carry more of a load) than a 1' pipe Effort to punch through the pipe is likely the same, but bending strength is way higher. There is more steel in the 4' pipe.

But from the inside out, pressure wise, isn't the thinner cylinder stronger?
Not sure that has anything to do with the ability to maintain a seal.
But, of equal quality glass, a "set it and forget it" scope, the 30 offers zero advantage?

From a business standpoint, there is a big advantage. First you convince everyone that they need to replace their 1" scopes with a 30mm scope. Then in the future you convince them that they need to replace their heavier 30mm scope with a lighter 1" scope. That is a big boost in sales.

You will have to ask the owner of a Swarovski Z5 and a Z6 one that has a 1 inch tube with 1inch internals and the other with a 30mm tube and 30mm internals and yes the same exact zoom range.

John This. Provided the 30mm has 1 inch internals there is more room for w/e adjustments . No european scope from the big 3 has 1 inch internals.

Not necessarily look at a Zeiss Victory HT with its glass and optics and compare it to a 1 inch model from the same manufacturer. It is lighter. Switching scopes without switching rings...I use Talley detachable screw lock rings , I can put anything I want on my rifle depending on where I am at. Which 30mm scope made by the big 3 alpha companies has 1 inch internals?

Not a Swaro, but when comparing a 3.5-10x40 VX3 (marvelous hunting scope IMO), with a 2-12x42 VX6 (marvelouser hunting scope) 1" vx 30mm (obviously), I can report the following:
VX6 advantages: more forgiving eye box across the zoom range, especially at highest mags, best of any scope maker anywhere at any price that I've personally seen. Better glass, better reticle, more W/E range, relatively lightweight for a 30mm tuber.
VX3 advantages: smaller package, W/E adjustments are "clickier".
It is irrelevant what you think. What matters is the TRUTH.
