Hi carbonbased,As far as just thinking about this problem, @koshkin has an article on his site (or perhaps one of his sites; not sure how many he has now) that talks about scope Durability vs Repeatability. I cannot link directly so you’ll have to use the “find” function of your browser once you are on the page.
I think you have a very good point about confounding factors when trying to get to the bottom of why a rifle loses its zero. I remember the post you mention…I’ll try to find it.
As you say, there is a “practical” holding of zero (how does a scope hold zero on my rifle?), which people mainly discuss and that really involves a whole system: rings, torque, scope, base, bedding, etc. And then there’s the “absolute” ability of a scope to hold zero (just the scope). You may quibble with my word choices but you get the idea.
To really test that last bit, I’m sure there’s a way, but I’m not sure how a regular dude could test it. As you throw the scope about you cannot have it mounted to, say, a Badger Dead Level (BDL), as then you’re going to be simultaneously testing the rings, the ring torque, the BDL, and the ring base torque at the same time. This is not even considering the fixture you’d have to build to index the BDL at the target once you’re done with the abuse. All you’ve eliminated is the rifle bedding/barrel-receiver interface/rifle’s scope base etc.
But if you cannot have the already scope attached to anything (rings, rifle, etc) in order to test how well it (and only it) holds zero, then how can you know if the zero has shifted? Scope manufacturers surely have extremely solid fixtures with a repeatable mount of some sort that stays pointed at the same spot in space. Perhaps their mount does not even squeeze the scope to isolate even that variable.
Unless you already have a rifle/ring/base/bedding/barrel-receiver-interface/etc that you somehow KNOW is so solid that you can confidently rule out those factors…? Again, beyond most guys’ ken.
I don’t know, but I’m sure koshkin or other engineer-y types have an answer. @E. Bryant
Interesting. Are you the one-and-same as Formidilosus on rokslide?Hi carbonbased,
I think you'll find most of your questions are covered in the original thread.
Ryan from Rokslide is going to supply other scopes to be tested; the first being his own NX8.
Some more background on the test approach is here: https://www.rokslide.com/forums/threads/scope-field-eval-explanation-and-standards.246775/
Nope.Interesting. Are you the one-and-same as Formidilosus on rokslide?
And he has been testing these optics this way for a while.Again as stated above he basically only had nightforce and SWFA pass the test. The TT he tested was bad.
That would certainly give a much better idea of it.I think the simplest way to check the rifle vs scope is to do the same test with the same rifle with a different scope. At least at that time it’s narrowed down to scope and rings vs the entire setup.
If I do this again I’ll take another scope or two and mount them and do the same thing. If they all shift then I would say it’s a good chance it’s a rifle issue. If it’s only the Vortex then I think it’s pretty cut and dry on where the issue is.
Is he a troll then? Or actually an idiot?My mistake doesn’t seem banned but lowlights comment is what I’m talking about.

Is There Any Truth To This Claim
The PRS “stats” on face value should be taken with a grain of salt. Unless you know the politics and inner workings you’re not seeing the what you think you are. For instance- if my life depended on it I would choose a Bushnell HDMR over most current production S&B’s as they have fewer...www.snipershide.com
His other gems include but are not limited to: barrels of any diameter do not change group size when heated, and extra shots rapidly are simply showing your true “cone” of accuracy and my favorite is that barrels do not need to be cleaned at any point in their lifespan, not for accuracy nor to increase barrel life. This of course is contrary to what every world record benchrest competitor thinks, and contrary to what Frank green went over to rokslide and wasted his time explaining one day.
Hey, no problem, I get it. I found some posts by the fellow that were interesting:I’m not gonna go back through his posts and dig up dirt nor do I have a list of times he’s said something suspicious, shouldn’t have participated.
His thoughts on barrel cleaning are pretty evident on his profile, and he seemed to often claiming extraordinary round counts. There is a consistent trend that only nightforce, Swfa and bushnell make good scopes. Whatever, again I need to learn to just not post as rightly people will want evidence/examples and it’s not worth the time.
The turrets on the LHT HD, especially the windage are atrocious. I have better turrets on 100$ Chinese Weaver. It’s one of these scopes that looks nice on paper because they check all the boxes but the execution and the compromises in the design ... enough said. Almost ruined my hunting season but I was lucky I caught the issue in September.As anyone who has handled a lht 3-15 would appreciate, they feel lightly built. Almost inexcusably cheesy turrets. The kind of optic you would imagine not surviving a fall from waist height in the field. AFAIK g2 lht uses same quality turret and 5x erector. Not sure what else one would expect??
Let me see if I follow what you're asking for. Because you're considering purchasing a specific optic you would like someone from this community who owns this model optic has already, or is willing to purposely, repeatedly drop said gear to test to see if it is damaged by said negligence?Has, or can anyone do a durability/tracking test with the new vortex lht 4.5-20 or even a 3-15 model?
Some guys on another forum are claiming significant zero loss after dropping the mounted optic like 6" on snow.
I'm considering this scope and would really appreciate some more testing from a more respected forum community

Really??
You’re new here. If you board your way back machine you could watch Lowlight drop scopes, crank the turrets and blow them up. I think he even gave the blown up Bushnell away to a member that had the best hard luck story.Let me see if I follow what you're asking for.

I haven’t read rokslide much. Most of what I’ve seen from and of Formidilosus has been on 24hrcampfire, it’s the same stuff. I don’t care who he has helped, he could help little old ladies shoot across the road. The guy is not to be believed, at all [full stop]
Just throw it on a AI for the testUnless you already have a rifle/ring/base/bedding/barrel-receiver-interface/etc that you somehow KNOW is so solid that you can confidently rule out those factors…? Again, beyond most guy

I haven’t, been slammed with work and I’m waiting for my 4.5-22 to show up. It seems like there are lots of guys that aren’t having any problems so I may just be unlucky.Did you ever get a chance to go out and use it again? I put one on my NRL hunt gun that I’m taking to a comp this weekend and I wanna know if this will hold up or if I need to swap to something slightly heavier but more reliable

Go drop it on a mat a few times in the yard if you have time to check zero before your match. I would be interested in knowing if my experience is at all common. The more scopes checked the better imo. If a bunch of guys check theirs and have failures I’m gonna explore options that I know are solid. The weight of the LHT’s is really tough to beat so I want them to be reliable as much as anybody else but I’ll pack that extra 10oz if I’m confident in it.
Will you elaborate on how you would make a scope pass or fail?I've been involved in designing equipment for durability testing of this stuff and I can tell you right off hand that the way he does it I can make any scope fail or any scope pass. It is as simple as that.
Thank you for weighing inI talked to the gentleman in question a couple of years ago. He seemed like a perfectly personable guy, but his results do not jive with mine. I also have the advantage of knowing the return statistics of several manufacturers. What he says about scopes sounds plausible, but does not jive with with what I have seen and what I know about the statistics of this. It also does not jive with the experience of a couple of fairly large armories I interact with for my dayjob.
I have not read everything he wrote over the years, but enough to think a lot of it is at least embellished (hunting stories) or out right silly nonsense (some of the scope tests). He does a good job of making them sound scientific, but it is really too uncontrolled of an experiment to make conclusions out of. I've been involved in designing equipment for durability testing of this stuff and I can tell you right off hand that the way he does it I can make any scope fail or any scope pass. It is as simple as that.
Beyond that, he clearly has a beef with Vortex. I do not know the origin of it, but he has never managed to find a Vortex scope that works. Not once. That's one hell of a lucky streak. He also has never managed to find a Nightforce scope that wasn't flawless, indestructible, etc. Is he a Nightforce shill? Perhaps, but he also likes older LOW designs like the SWFA SS HD and Bushnell LRHS/LRTS. I know with good amount of certainty that he does not have any personal relationship with the folks at SWFA. In other words, I have no idea where his bias comes from, but I know he hates Vortex with a passion.
He either does or did work for the military. Sometimes, he talks about it all the time and other times he goes all secret squirrel about it. I did not bother to check whether that is true or not, but he does like to sound mysterious.
He goes from forum to forum and bashes companies he does not like in more or less the same way. I know that on at least a couple of forums he got paid to stick around, presumably because he spins a nice sounding story and attracts an audience. Since it is always some form of the same nonsense, I sorta stopped paying attention to him a couple of years ago.

Appreciate the insight. I really hope this optic is solid, I want it to be. Im nervous to take it with me to my match this weekend. I may have to make time on Thursday and just see how it holds up. Not ideal to test this a couple days before I shoot it but peace of mind is priceless
To clarify: I have seen scopes from every manufacturer crap out due to manufacturing variances, random abuse, etc. Some product lines are better than others, but between the Razors and other good quality Japanese scopes from the same OEM, it is hard to find any statistical difference.Thank you for weighing in
This is exactly why I brought this topic to the forum it needs credible input.
Your summary of that guy jives 100% with my impression, I've read some silly and outright pure disinformation that he's put out.
This seems both logical and reasonable. Reading through many of the comments on rokslide it seems like there is a lot of vortex hate. I am neither a fan or hater of Vortex as a company, this particular scope just fit the niche I needed for my rifle and I do like it so far. However, reading people on that forum say things like "vortex is a modern tasco" and "vortex is just a good marketing company" really pushed the boundaries of absurdity; I understand tolerances and OEMs building things to the companies specs, so just because it's Japanese made doesn't mean everything is the same, but acting like Vortex puts out or even designs their stuff to be chinsy intentionally is extremely overboard. To be fair the tester did not say those things, but that definitely seems to be the vibe there in that particular thread. All things made by men will fail or can fail, I will continue to keep an eye on mine objectively, but the concern people are having so far seems to be blown out of proportion. Cheers fellas, I'll report back next shoot day as mine has taken some good spills recently since shooting, lol.To clarify: I have seen scopes from every manufacturer crap out due to manufacturing variances, random abuse, etc. Some product lines are better than others, but between the Razors and other good quality Japanese scopes from the same OEM, it is hard to find any statistical difference.

No kiddingThe Vortex hate over there is but ‘tis a scratch compared to the whupping Leupold gets lol ow ouch
It’s no different than the Harris bipod or IOR bashing around here.. bitching about stuff and the Internet go together like pb&j, lolNo kidding
I was pretty shocked at all the mk5 bashing on that site..
Literally the first time I'd heard of them having issues, not that I don't believe they fail occasionally but it seemed every other guy on there owned one that crapped out.
LMAO at some of the clowns over there
Now I have to know what 8 optics in a row failed on you!It’s no different than the Harris bipod or IOR bashing around here.. bitching about stuff and the Internet go together like pb&j, lol
While not nearly the sample size as many others here I had 8 optics in a row from a top tier manufacturer ( not vortex ) all fail within the first 6mo. of owning them. I can’t give any logical explanation of why other than Murphy working overtime. Nonetheless I won’t buy another.
I don’t discount someone who has had a run of bad luck with a particular manufacturer, but I do keep in mind that the person is likely one of several hundred thousand.
Shit and Bender fo shoNow I have to know what 8 optics in a row failed on you!
I have a shooting mate that had a fucking nightmare trying to get his NightForce repaired/replaced.
They simply wouldn't admit it failed, then wouldn't tell him what went wrong with it.
