IMO, you don't need 30mm and you'll hard pressed to beat these deals from the samplelist.com

Sort of, kind of. The fact I like, is increasing the diameter of the tube increases its strength to weight ratio. Keeping wall thickness constant, going from 1" to 30mm roughly doubles strength and stiffness in bending and torsion while only increasing weight by about 20%. A slight reduction in wall thickness can give you greatly increased strength at the same weight--although dent resistance would go down. But you get the idea. No, not needed for most. But as one who bent the 1" tube of a scope once bad enough to render my hunting rifle worthless until re-zeroed, that is something I consider. Especially when the scopes are long, high powered ones with large objectives as simple leverage makes them more susceptible to damage, they can benefit from greater strength in the middle. |

they make 1" tubes???? just kidding--- I put a youtube video on this site a while back showing the flexing a S&b scope goes through when fired over a 50, while most scopes will never see this much flex, never the less the tube of scope acts just like a steel tube that is fixed on one end and gets whacked with a hammer each time its fired, the vibration dampened curve (single beam) are well studied and impulse (control system technology) is well documented.
better scopes are heavier because the entire erector sets are made heavier, not just the glass which only contributes a few oz. and the increase in tube wt. is also small.
regardless how one feels about 1" tubes--- it still dates the era when it was made, and because of recoup of fixed manufacture costs will always sell at a bargin price. (not good or bad just is)

I understand the points about the 30mm tubes...........After thousands and thousands of range rounds and dozens of hunting trips over nearly the the last 40 years, the 1" scopes I have used have never let me down in terms of holding zero, abuse, recoil issues, durability, or performance. If so, through either my fault or a defect, then a new one under warranty, more than likely, would have simply replaced the old scope anyway!
The clear optical advantage for the 30mm`s begins when the price tag goes way up to, at the very least, a grand or more depending on the scope.
With a budget of around $600 or so, there is absolutely no reason why a great quality 1" tubed scope priced in that range cannot offer a lifetime dependable use.

And for $600 I think a person would have a tough time finding a scope that is better optically than a Meopta Meostar. Meostar's do have amazing optics. I have two meostar products and they are fantastic. You get more than you pay for with them.

the following is not meant towards anyone just that the 30 mm can be searched (squeeze to dont take this personal as you know how I feel about scout scopes set ups) off topic here, but does anyone remember the old 7/8" and 3/4" tascos,bushnells,weavers from about 20 years ago. had one mounted on a blowgun with a b-square win. mod. 92 scout barrel mount-- perfect proportions.

Mine is on a 7mm and I have yet to hit myself in the eye. It was on my 45-70 for a while and I never hit myself with it there either. I think Meopta is pretty low on their listed eye relief. They probably list the very very bottom end of the variable range.

I have a Meopta spotting scope, got it from the Bargain Cave while I was still an employee - great discount..... it is great for what I use it for, but so far I'm NOT a big fan of their scopes, mostly because of the eye relief. It seems like the stated value is right and its not enough for me!

You two both seem to be real big on the eye relief, must have been smacked a few times.
It must be the way you hold the rifle to your body. You must be kinking your neck down to much to get into the scope. That will make it like you are shooting up hill. The scope/rifle should actually come to your eye, if you are bending your neck at all you are not holding the rifle to your body correctly or your rifle/scope is not set up correctly.I can see the need on some of Squeezers big bore's the importance and the long eye relief. But not for 99% of hunting rifles. If you are holding the rifle properly to your body, you are just not going to get smacked. |
