I guess I just have a difficult time looking at buying a scope that costs at least twice what I paid for my rifle? James Cook Gold supporter. AH veteran. For what it's worth - asked our PH about mid-tier brands Nikon, Vortex, etc. His response was a good quality mid-tier scope was fine for PG safari. So in his opinion top tier scopes for PG not necessary - just bring a good quality scope that you have confidence in and shoots accurately.

Why a 30 mm tube on scopes with objective bells The 30 mm tube choice has nothing to do with light transmission. The only advantage a 30 mm tube has over a 1" tube on a scope with an objective bell, is that it allows more room internally for a wider range of adjustment of the scope erector, i.
A definite weakness The reason why virtually all modern military scopes have 30 mm tubes is similar, but applied to a different purpose. More internal adjustment allows more elevation clicks to shoot farther.
The reason why some military scopes are now available with 34 mm tubes is more of the same: more internal elevation clicks for latest longer range loads e. Lapua, etc. Why a 30 mm tube on scopes without objective bells First we need to explain a little more the exit pupil concept. Yes, human pupil vary in diameter from 2 mm to 7 mm, but the application of this fact has nothing to do with the tube diameter, because indeed whether the tube be 25 mm, 1" Bert the Turtle is correct!
The application of the basic rule that a 7 mm light beam must desirably reach the pupil at full dilatation in low light condition applies to the diameter of the objective. The basic rule is that magnification x light beam diameter determines the diameter of the objective. This is the reason why a straight 1" tube DG scope with 20 mm objective on a. Regardless of glass quality, a 1. This typically means 5 to 10 less minutes of shooting light at dawn or dusk, and that may make all the difference in the world, where legal Everything else such as glass and coatings quality being equal, you will factually see a Leopard at dusk, or a Kudu at dawn, better with a 42 mm objective than with a 20 mm objective because a 42 mm objective will collect a 7 mm light beam at 6x and a 20 mm objective will only collect a 5 mm beam at 4x.
The best glass in the world, from whichever manufacturer, will not make up for this. A straight 30 mm tube DG scope with 24 mm objective is a step in the right direction. At 4x a 24 mm objective gives you a 6 mm light beam. This is not as good as 7 mm, but this is appreciably better that 5 mm. I personally play the game on both ends: I use a 30 mm straight tube because of its 24 mm objective, and I rarely use it at more than 3. This is not because they are better quality, but rather because of the misconceptions that 30mm scopes are just "better," and because of slightly higher production costs.
So if you want a good scope but are limited by price, don't worry about the size of the main body tube. Get the scope you want, and a set of rings that will fit. Minox ZV3 Rifle Scopes. Follow us on Facebook. Newsletter Ok. What do the numbers mean? See the image below for an example: What is the difference between 30mm and 1 inch scope tubes? Is a 30mm scope better than a 1 inch scope, or vice-versa? Are 30mm and 1 inch rifle scopes interchangeable? Do 30mm scopes provide better light transmission?
Why bother with a 30mm tube if 1 inch is just as good? When shooting "set it and forget it" capped turrets, I have not noticed any difference in performance between 30mm and one-inch scope tubes. Most believe the 30mm will yield more light transmission, but I do not believe that is necessarily true across the board. Historically I have used one-inch, set and forget scopes because the terrain I hunt rarely gives me more than a yard shot opportunity at deer.
Generally, one-inch scopes and rings are less expensive than 30mm equivalents. Joined Jan 15, Messages 8. I prefer the 30mm tube! The one inch tubes are also lighter. Ugh not sure what to do.

Worst one of the fleet. A 30mm Sightron I have is awesome however. Best thing to do is look through a bunch of them and make up your own mind. Scopes, like any optic, are different for many. Joined Mar 29, Messages Location Wyoming. That's it. Doesn't affect light transmission. If you are shooting at yds, even yds and in, you aren't going to run out of turret adjustment.
All my scopes are 30mm or better. I dial That being said, generations of hunters, including many of us here have used 1" scopes for decades with great success, and many still do. If a 1" fits your needs and budget, go for it! I like that the 1 inch scopes are lighter. The ideal range is 0. So another 14 mm on the radius.
