Same, didn't take it personally. I loved the 3-18 when it came out, no one had anything like it, and the MP-8 reticle was my favorite at the time. It wasn't till the nightmares started that I lost the will to own anything IOR.

I have not run anything of their 40mm tubes. I know when the 35s came out, they had some severe issues, not sure if they worked them out or not.

If the shift is consistent and reproducible, I wouldn't worry about it. If it is a wind thing, as someone said above, you can dope wind on the reticle. I'd be more worried about a bad wind call at range than I would how to adjust properly.

No prob.  I didn't take it any way personal, just that I had first hand experience with failures is all.

The only other thing that has just popped into my head is that Recon is shorter than the Crusader. By my reasoning on this with it being further back the angle deflection if mounting related would be greater. But would it so great to make a 10cm difference at 50m's.

I have tried mounting and remounting twice with the exact same results. I have also tried mounting them on 2 other rifles and the error drops by 2 mils to the right but still has the 2 mils error between scopes.
I am being to suspect that the 1 piece mount is out by 2 mils. But again this does not account for the 2 mils between scopes.

Guys it was not a personnel rebuff on either of you. So I apologise if it sounded that way. Where your experiences in the last 2 years and where they on the 40mm tubes. If the older models suffered with problems is it reasonable to judge the rest by that experience.  I spent a long time looking up what scope to purchase and found that the scopes were generally held in high regards. I did not find any negative reviews in relation to the Crusader and Recon. Customer service now that may be a different matter.
The problem that I am trying to get to the bottom of may have nothing to do with scopes and more to do with something that doesn't really exist. Alternately it could be a compounded error between rail and gun. I just don't know which it is.

I missed that too. I personally went through 4 or 5 3-18x’s before i got one that performed properly or didnt fail.

Don't take this the wrong way and I am valuing your input.
I hear a lot of people stating that IOR scopes are inconsistent or rubbish. However they generally don't back this up with fact. Nearly all the comments come from America and not Europe. Yes there is 1 or 2 but that is the same with S&B, Vortex etc. But it seems that it's always someone they know and not the person who owns the scope. 




I'm not sure how I missed it, but I missed it.

And to be sure I understand it: you, an IOR optics owner, are seeing a strange thing in your scopes that causes you to wonder if they are functioning properly. Simultaneously, you are chiding me for saying IOR has a well-earned bad reputation for optics and customer service. Is that the correct context?

I've owned several IORs including the gen1 Sniper's Hide 3-18 - of which the entire batch failed due to a faulty metal component. All were replaced (I think, mine was) but replacements also had a high failure rate, and getting them took a bit of time.
I have owned several IORs, a few had issues, customer service was generally non-existent; and when issues were addressed, it was always solved by shipping a new scope from eastern Europe. I had enough failures and CS issues that I stopped buying IOR scopes.

These are my experiences, from my IOR optics. Some people still own them and love them, great; my experiences were far less than positive.

In contrast, I have also had a few issues that had to be addressed by Vortex, Swaro, Leica, Zeiss, and Bushnell; all were orders of magnitude better experiences than with IOR.

With a .308 at 1100 with a full value 25mph wind you would need about 6.5 mils. Your scopes will still be just fine even with the 2 mil difference.

If you shoot on that day with that gun in those conditions, the scope will only be a minor player in a very dramatic play.

I have never been one to worry or care how close a scope is to the mechanical zero.  As long as I have enough adjustment to compensate for the type of shooting I am doing with that rifle/scope combo there is really no need to care.  Some people go to all the trouble to set their scopes to the mechanical zero before mounting them.  Why.  There is only a small chance it will stay at that mechanical zero.  They are not meant to, that is why there are adjustments.  There is just no reason to worry about it unless it is affecting your shooting. 


Thanks and I think you are probably right and I am only caring about it from a perceived shooting of a 90 degree 25 mph wind at 1100 yards. Which is probably not likely but you never know.

Your rifle and caliber are solid, IOR has a long and troubled past with scope quality.

If they hold zero and track true, you have to decide if the windage issue is enough to make you move to another brand. 
Yes they track true and hold zero. I am just trying to get to the reason for difference. Not really wanting to change scopes.

Did they offer an explanation and how close was the second.

Tikka makes a good gun, what caliber?

How does the vertical 20MOA affect the horizontal? Gun is in 6.5 Creedmoor.

IOR's are not known for manufacturing consistency.  I stopped testing IORs quite a while back partly because of that inconsistency: I can't make recommendations if I do not have faith in repeatability of the product.

Given what you are trying to do, you are expecting too much from your scopes.
