[Updated:] OK, I'm going round and round with the elevation adjustments of several Discovery scopes:

HD 34mm: 4-24x50 and 5-30x56

HD 30mm: 5-25x50

[The second and third scope come up further down... ]





Discovery: HD 34 series

4-24x50 | No. 170109





The manufacturer on different webpages proclaims not one but three different maximum elevation adjustment ranges:



● [85MOA=] "25MIL" | By Mfctr, here [webpage disfunctional now]: http://www.discovery-optics.com/index.php?m=Product&a=show&id=185



● [85MOA=] "25MIL" | By a seller, here: https://airgunopticsplus.com/products/discovery-hd-4-24x50-sfir-slt-ffp-ir-mil-tactical-long-range-shooting-hunting-riflescope-34mm-tube-first-focal-plane-rifle-scope 




● "40MOA" [=12MIL] | By Mfctr, here: https://store.discovery-optics.com/products/discovery-hd-4-24x50-sfir-slt-ffp-ir-mil-tactical-long-range-shooting-hunting-riflescope-34mm-tube-first-focal-plane-rifle-scope




● [58MOA=] "17MIL" | By Mfctr. in UK, here: https://discoveryoptics.co.uk/home/rifle-scopes/hd-34mm/hd34-4-24x50-sfir-ffp



● "40MOA" "25MIL" | By a YouTuber who threw himself into the fray of elevation adjustment claims that "25MIL" is really not much for this 34mm scope as this would be "40MOA in the imperial system." 

Unfortunately, he got it wrong, as the conversion formula from MIL to MOA is factor 3.43, so..... 25MIL x 3.43 = 86MOA 


[at 7:05min in the video. LINK: You need to add www. to the following addres if you want to go to the link:] youtube.com/watch?v=DerSb0Y-d34 








Would somebody who owns the scope just dial the turrets and get a real life value for the max. elevation adjustment?

(Maybe you could also supply a purchase date -- sometimes the mfctr make changes...) 





While you're at it 😃: The UK website says it focuses down to 10y, other websites say to 15y. Would you physically confirm what its min. parallax is?



THANKS A LOT! :)

Add to that, their category says 50MOA. Now, their ED 3-15x50 says 80MOA with a 30mm tube!



I was also looking at the new Strike Eagle 5-25x56 by Vortex. Specifications say 110MOA elevation and 78MOA wind. They due note that with the zero stop installed you lose some elevation adjustment. 


What do you think about it? Sorry to side track this thread!

Funny you ask, just yesterday I added that to my Scope Specs Lists.

🔶It has a FoV of 24ft @100y, that's somewhat less than the 27 Discovery, but not that much.



🔶It has a 56mm lens (≠50mm), to the eye box will be larger = easier to find and keep the scope image. And you'll get more light in.



🔶It has whooping 110mil elevation adjustment range, you'll be hard pressed to max. that out.



🔶The turrets turn 10mil per revolution (≠6mil) — so you won't be having to count revolutions for long range shots unless you do some extreme shooting — and then you have a zero stop to find your original zero (none on the Discovery).



🔶It has a grid style reticle, if you want that (≠ D.). And you can have your flavor of MIL or MOA with it (D = MIL).



🔶It weighs 8oz more, and is about 1" longer than the D. 



🔶The reticle lines are 0.03mil thin, the D's lines are 0.05mil thin. Both are FFP.



🔶The glass is probably "very very good." I expect the Discovery glass to be "good" — it's the HD line, and there is a lot of praise for Discovery glass.



🔶You can buy ONE Vortex — or you can buy TWO Discovery's.

Yupp, the Vortex is double the price.

🔴 OK, now back to the Discovery HD 34mm 4-24x50 and its contested max. elevation adjustment and min. parallax. 😄

Thanks for that, Jim! 👍🏼

50 moa max. elevation adjustment for a 30mm tubed 5-25x scope is kind of average, on my scope lists most have 50 or 60 moa, with some 70 and 80's.



The 4-24x and 5-30x have a wider magnification range than 6-24/5-25x — so they should be worse — but in fact they are mostly better: 70's to 110 moa(!) (with a couple low 40 and 50 moa, on the lower price class).



Now a 34mm tube scope with similar magnification should have more elevation adjustment range — as the tube has a lot more space for the adjustment mechanism.... 😊 



Really looking forward to the answer of Discovery — thank you so much for contacting them, dc8cappie! 😄

❌ Ooooops...! 😟

Just looked at a couple different websites for Jim's HD 5-25x50.... — 'cause that's a close contender.

Look at this ridiculous inconsistency...!



▪"20MIL" = 70MOA, at Discovery's UK site, here:

https://discoveryoptics.co.uk/hd-second-focal-plane/hd-5-25x50-sfir-sfp/



▪"60MOA," at Discovery's direct sales webpage, here:

https://store.discovery-optics.com/products/discovery-hd-5-25x50-sfir-dltw-sfp-ir-mil-tactical-optics-riflescope-shooting-and-hunting-rifle-scope-with-illumination



▪"50MOA," on the specs card that shipped with the Discovery scope (thanks, Jim), here:

https://www.airgunnation.com/topic/discovery-hd-34-4-24x50-elevation-adjustment-what-40moa-58moa-85moa/#post-699075





Wow, I really would like to trust manufacturers when they state objective, verifiable data — 

or at least, I'd like them to lie consistently to me, or something... 😖
