No, not in the shooting sports for sight adjustment purposes. But I do accept the fact that it's not 1.00 inch per hundred yards for other angular measurements using trigonometric functions. I can deal with three different amounts for a mile; a nautical mile being exactly 1,852 metres or almost exactly2025.3678... yards and a statute mile being exactly 5,280 feet or exactly 1,760 yards. Then there's the US Navy radar mile of exactly 2000 yards which was used for decades to simplify ranges used for both navigation and weapon systems.

I'm not surprised that tech didn't know. A tech at Burris answered the same way when I asked about their scope's adjustment standards.
I'd want to find out why their published specs say the adjustments are in fractions of an inch (1/4th or 1/8th) at 100 yards and their "wizard" said it was angular if angular meant one MOA's about 1.0472" at 100 yards. I think it's a bad thing to do for the same company to put out two different answers for something that's only got one. Their mil spec'd scopes are supposed to move the reticule 1/10th mil per click; .360 inch at 100 yards based on 1/1000th of the range so now I'm wondering if their "wizard" might want to claim those also use the MOA system. I would be very interested in finding out how they would correct it and if so, to what new value.
I'm going to email Sightron asking them what the tolerances are on their scope adjustments.

An e-mail would be good! I'm going to call them again and ask them to explain the mixed specs and ask them exactly how they intend to fix the problem with my scope?......rich

I just got off the phone with Sightron again and here is what he said. Some of the scopes are angular and some are not. It sounded like mine was but after I got off the phone, it seemed as if the turrets were angular measure but the 2 moa reticle was in inches? Not sure of that? He said to send it in and he would put it on the collimator and determine if it was within spec? I asked him what spec was and he said about .259" which is only .003" short of what mine is. I asked him if I send it in will it come back closer than it now is and will they do whatever it takes to accomplish that? He said they would correct it by calibrating if possible and repair or replace if not........Rich

It's total BS..
All scope adjustments are angular, whether actual MOA or any other.
You've listened to Bart, got your terms in the mud, and now Sightron reps are struggling to satisfy some crackpot on the phone!
What they will find is that your scope meets their criteria and tolerances. If you corner them, they will just grab another scope off the line & send it to you, with more made up BS.
Then when you test the new scope, you're just as likely to find it departing MORE from actual MOA.
Of course I can't prove this. I'm just blurting probabilities here..
But you are very close to MOA adjustment now, and despite, you know the value in IPHY.
It would be a good idea to check your reticle and determine what's what. Sightron isn't going to redesign that, so you need to know it if you're gonna to use it in the field.
That is, the LONG RANGE HUNTING field.

Remember you got .2625" per click at 96 yards and he said spec was about .259" which is probably at 100 yards. At 100 yards, your scope will move impact a bit over .2734". That's almost a 5.56% error from that .259" spec.
I've no idea where that spec measurement comes from. To me, it has no relationship to mils, inches per hundred yards or angular MOA's that are 1/60th of a degree.

Well, I appreciate your input, as well as Barts' and I will make a decision as to what to do next when I get my scope back....thanks/Rich

Good point! I might have missed that. I guess the bottom line for me is wait and see what they actually do and see if I can live with it...thanks/Rich
Thanks, Mike.

Mike.....I don't think this is a fair assessment! I think Bart has a lot of credibility, as do you! Neither do I think it is fair to call the tech at Sightron a liar. Both you and Bart impress me as intelligent individuals with some good input. This may not endear me to you, but I think where you fall short is trying too hard to show people how intelligent you are! Lighten up

You're right rich.
Bart, I should not have blurted that. It's not true, and I'm sorry.

Mike......I just gained a much greater respect for you! I'm certainly not above these things and is probably why I recognize it
. God bless you!......Rich

Bart i tested my Mark 4 today and came up with .2666 per click. a 2% error
