Home Forums Hunting & Shooting Hunting Optics Advantages of 30mm Tube ?

Sorry I haven't kept up with latest advancements in optics, heck one of my rifles has a steel tube K-4 Weaver,I noticed Bushnell's price list had mostly 30mm tubed scopes. JB mentioned something in passing that triggered my curiosity.

Erector travel, beefier internals which have proven to be much more reliable vs 1” offerings.

If I’m not going to be dialing, I see no real advantages.

More weight and bulk, Some likem big and heavy

DT2- the 30mm can be lightweight but if you want longer range get a 1" tube. The smaller 30 MM tube gets you less elevation clicks, the 1" gives you more elevation clicks and the apprearence of more light transmission, but you pay for it in weight. Seems like the difference is what distance are you planning to shoot and how much weight do you want to carry. Good luck!

Several things wrong here.

Got that backwards: 1" < 30mm. Some of the more popular LR scopes are going up to 34mm and 36mm tubes now.

i kinda feel the 30 tube scope is better for heavy recoil too over a 1 inch tube in the better brand scopes or just better stronger adjustments that stay on target better sighted in ?

If that's not enough, the long range guys are using 34mm tubes...

You sure about that?

In addition to the previously mentioned, 30mm tubes have a stiffness advantage over 1”, as well.

And larger as well.

After using 34mm tubed scopes, looking through a 1” or 30mm tube seems like looking through a straw

Really depends on who makes the scope, and things like objective lens size and magnification. A 1-4x24mm in a 1" tube is likely going to be pretty sturdy, but a 5-25x56 with a 1" tube is going to be a lot more floppy than a similar 30mm tube scope. Scope tube diameter doesn't guarantee internals durability (as Vortex and Leupold can attest to - plenty of issues with their 30mm tube scopes in regards to durability and holding zero even on non-boomers).

Can you attribute that to the 34mm tube per se?

I guess so. Try it by looking at a few mounted on rifles, side by side.

I'm not doubting what you've seen. I believe there's more to it than just the tube diameter. Side by side with a couple of 1" scopes can show significant field of view appearances.

Almost sounds like some sort of AI or English as a second language at least. Other posts are as odd.

I do like the handle “blammo”, though. 😂😂😂

Everything a 1” scope does, a 30mm does better. But I do also think there is a point of diminishing returns. I personally see no need for 34m+, at least not in a hunting scope.

i have had excellent pin point accuracy with my Nightforce 30 tube scopes they stay zeroed in and even on my 338 Lapua .

Those have a positive reputation for toughness.
