[MENTION=63862]calz[/MENTION] I think your math is off on the difference between min/max eye relief for the Kahles. You have it at .3 when the values are 2.6/2.8.

Surprised to see how poorly the Kahles 624i did in optical clarity, especially after many posters saying the glass was better than the S&B PMii 5-25.
I've had a demo, and have a new one now. I think under 100 yards the S&B has better glass. It's pretty clear when I had them side by side, but at 300 yards I could not resolve any more detail out of the S&B. The Kahles also had a more forgiving eye box, but less eye relief. Kahles had IMO better FOV (this optics shoot out agrees with that) and no tunneling.
Is it "better than S&B PMII 5-25 glass" I don't think it is, but I feel overall they have different features that make them pretty even, it just depends on what you want out of the optic.
Just for me to understand the method -- how exactly do you define "appropriate"?
I wondered about that myself. I have had several of these scopes and while I don't claim to be any kind of expert or have the ability to run these detailed tests, my personal rating of the optical clarity would be different. I wonder if there really is a lot of difference from scope to scope that could explain this?

Mr. Zant, you are a man of character. You do all of this work for free, get a ton of crap from people who got butt hurt about how their own personal scope did not do well, and still carry on with reasonable responses. I am very impressed. The industry here needs more people like you. Well done. Thank you.
On this particular site I've never read anything positive about IOR' s, but on this very unbiased test they seem to be doing very well?
Not to mention the effects of weather swings, the elements, and imperfect handling. Actual use of a scope is very important, and even that won't tell the story all the time. I had a scope that took 2500+ rnds of 308 that crapped out within 50rnds of 338LM.Theses are rifle scopes not spotters, everything works perfect when you hold it in your hand. Recoil is what separates looks good, from works good.
It's the difference between looking through it and actually using it on a rifle with recoil ....
It's why I don't comment on a scope until I have put more than 500 rounds under it. Theses are rifle scopes not spotters, everything works perfect when you hold it in your hand. Recoil is what separates looks good, from works good.
Not sure why you would weight the magnification ratio when you didn't verify the low end mag. Kind of violates the assume nothing principle.
Awesome videos. Something that's unique and very informative.
This is a great test we should all paypal this guy $5
Another update for Ergonomics Summary. The Ratings For Turret Design chart reminded me of reading Consumer Report magazine before the Internet.
Cal, What's your PayPal account name?
The reticle section is kind of disappointing. I would have liked to see photographs so people can see how the reticles actually look at say, low mid and the high end of the range. Some of the drawings don't even look like they are scaled right. The Leupold TMR that now comes with the Mark 6 3-18 is even suppose to be slightly more open in the center with a dot, not the clear aperture of the older TMR.
Hey Calz, in the latest entry I think you have the information concerning the Zero Stop reversed for the two Bushnell scopes. The standard DMR 3.5-21x50 doesn't and the XRS 4.5-30x50 does have a zero stop. If I misread the new Blog post I apologize.
I was thinking that the US Optics had a zero stop on the EREK knob.
Sorry for the confusion on this. Bushnell has a couple models of the "Bushnell Elite 3.5-21x50" and a couple of the "Bushnell Elite 4.5-30x50". This is similar to how Schmidt and Bender has 50+ different configurations available on their PMII 5-25x56. So instead of just looking at the DMR model, I wanted to show if any of them were available with zero stop. I actually changed the label to not include DMR or XRS, but I know this was confusing. I probably should have called it out, and I might go back and do that when I get a chance.
The Bushnell Elite 3.5-21x50 is available with a zero stop option, in their ERS model. It is virtually identical to the DMR, but has the Bushnell Z-Lok feature. Here is a link to their product page for that: Bushnell - ERS 3.5-21x 50mm
But none of the Bushnell Elite 4.5-30x50 models have their Z-Lok feature (at least none that I saw). Here is the product page for the XRS: Bushnell - XRS 4.5-30x 50mm

I'd be interested to hear what you guys thought about Double Turn turret designs. I broke those out as a feature, which I hadn't really thought of before.
The way I think about it, if you regularly get into the 2nd or 3rd revolution, you learn to double-check what revolution you're on often. Many shooters miss because they thought they were on a different revolution than what the scope really was set to. Typically, this happens when you engage long-range targets and adjust into the 2nd or 3rd revolution on the scope, and then forget to dial back down to zero before you start engaging your next targets. I’ve done it, and mental errors like that can be frustrating during a hunt or competition. It seems like a DT design makes huge strides in simplifying this, and also makes it a lot easier to design a revolution indicator, because its just a boolean indicator now (either you're on the 1st or 2nd revolution ... only two states to differentiate between). Some innovative revolution indicator designs from Hensoldt, Steiner, and Schmidt & Bender make that completely obvious. And you just need two rows of numbers on the knob. There just seems to be a lot of simplification that comes from this one small design feature.
What do you guys think about DT turrets? Important? Who cares?

You guys are killing me. I was about to buy a NF NXS8-32 with the MOAR-T. I have never bought a quality tactical scope and started looking around for some more info and boy did I find it. This is one of the best comparisons I have seen. Tactical Scopes: Advanced Features | PrecisionRifleBlog.com Like its too good!
All I wanted was someone to say ya the Night Force is the best choice out there for the money and you're making a wise decision - get the 8-32! Now I don't know what to do. I have a Millett 6-25-56 I picked up at the NRA show a for years back for 200 bucks. Seemed like a no brainer at the time but didn't have a gun for it so I bought a DMSP SASS in 308. I was shooting at our local range the other day and it was over cast and I could really tell that I was shooting a cheap scope. I have always wanted a Nightforce scope and can now afford it so was about to jump. Its hard to feel like I am making a good choice as I have never held any of these scope in hand.
I will be shooting mostly off a bench and punching paper or ringing steel. I like being able to use the rifle scope as a spotter and see the holes so the high magnification is appealing . I subscribe to the buy once cry once but after looking at everything and seeing the March scopes with the huge magnification range I feel myself being pulled that direction. I really don't want to end up with a couple high end rifle scopes... Any words of wisdom or encouragement would be greatly appreciated...
