Any advantage to 30mm as opposed to 1 inch tube other than more adjustment? Or is it like wheels (15-16-17-18inch-etc.) You know, making up for other "deficiency's".
A show of status seems to have trumped all sorts of common sense in this age of political correctness.

30mm will allow for more elevation and better durability opposed to a 1inch. Some will say light gathering ability, I wouldn't mind hearing why people think this.

30mm tube scopes allow for more W/E adjustment room, but that doesn't necessarily mean they have additional adjustment in reality. It all depends on the erector assy diameter, erector spring design, adjustment mechanics, and how much room is in the turret saddle.

30mm is technically a stronger main tube than 1", but in actual use, that "advantage" rarely, if ever comes into play.

30mm tubes in some cases permit slightly better resolution by allowing the designer to use larger diameter erector lenses and therefore less lens curvature.

Some scopes with complex optical designs simply aren't possible to manufacture with 1" tubes (extreme zoom range, for example).

The fact that some high end manufacturers only offer 30mm tube scopes and/or they reserve their best technologies for their flagship models (which are usually 30mm scopes) sometimes means you're getting a higher performance scope when you buy some mfg's 30mm versions.

Because a couple scope manufacturers at one time were making that claim for marketing reasons, and certain gunwriters were repeating this fallacy. On its surface, that sounds plausible when you compare scopes to other items the consumer can relate to, ex: larger diameter pipe = greater volume of water, etc.

30mm tubes offer no light transmission advantage vs. 1" tubes.

Are all manufactures eventually going to a 30mm or larger? Planned obsolescence seems to be the future.

Thanks Ted, makes sense. Kind of what I thought, just didn't want to post anything that I wasn't 100% on.

30 mm tube is not needed for Varmint scopes in my mind you sight in your scope at 50 or 100 and rarely touch the turrets after.  Also, they are generally low recoil guns so durability is not as big of a  factor.  It  would only add to cost.  I don't see 1" tubes going away anytime soon. IMO

That is why I only purchase 30mm scopes.

To each his own. I prefer to dial corrections.

May have been misunderstood, I was more specifically referring to something like a .22 used on rabbits or squirrels.  You sight in your gun at 50/100 and leave it.  I can't imagine someone with, lets say a 2-7x35 trying to dial to kill a rabbit with a .22 at 50 yards.   A 30mm tube would be pointless when a 1 inch can accomplish the same thing, in this case specifically. Don't get me wrong I am a big fan of a 30mm tube, just trying to point out a 1 inch tube is not necessarily obsolete. Like you said, to each his own (:

Depends on your definition of "varmint" and whether you dial in LR drops with turret or dope drops with BDC type reticle. I frequently use my "varmint rifles" to shoot prairie dogs, where shots well over 700 yds is very common.

I suppose 30mm or larger will make what I have obsolete and if that doesn't. Digital scopes or something like it will make everything else I am going to purchase in the near future obsolete.

Can't beat the MAN.

i would say never worry about what is technically obsolete provided it is still good for whatever duty you have planned for it.

i'm sure 30mm tubes have some advantages , but very limited advantages over a 1".

if it comes down to it a better glass 1" is better than a 30mm.

i like 30mm mainly because they fit the AR-15 mounts i have --so that is the big advantage to me.

not of enough advantage to prevent me from buying 1" scopes though.

we will probably see some even bigger tubes in the future  --with very high price tags on um.

 personally i don't see spending a lot of money just to get a 30mm, if it just happens to be a 30mm , that is also fine by me.

i got a very nice burris euro 30mm scope , but the 30mm tube is not what makes it tick --it is the good glass, coatings,  lenses and turrets that make it shine.

in some whys this is the same as the discussion about 50mm lenses , they do help in some areas but a good 40mm can certainly hold is own with it in most situations.

When it comes to looks, I am just the opposite.  On a nice light, trim rifle you mount that big old globby 30mm scope and it looks like chit!

Huh??

The difference between a 1" tube and a 30mm tube is .18 inches.

Most of the top quality tactical rings are available in 30mm but a lot of those are not available in 1 inch. 
We are seeing an increasing number of new tactical optics in sizes larger than 30mm also.

Also just because a scope has a 30mm tube doesnt mean that it is big and clunky.  I have this 30mm scope and love it.

Ok, Back on topic.
Yes, I agree.
In the pure marketing sense 30mm sounds much better than 1 inch better yet 34-35mm ~ why not 40mm. I have had many a salesmen pitch all of the above posts to "improve" my shooting, hunting and overall experience all together. Hell, my "smart" phone was obsolete before I even got out of the Verizon store ~ pretty sure my range finder and GPS are no longer relevant.

Leasing everything at a hunting and shooting club makes all the sense in the world ~ If you don't have expendable income.

I feel the coolest when I run a scope with a 34mm tube.
My frail ego can barely handle a 1" scope!
