The test was for poi holding ability not glass quality. Im still willing to test one of the 29x scopes for you. It may do well. So far what I have learned is poi holding ability doesn't necessarily correlate to price. However, I'll post my findings exactly as I find them good or bad.
Hello,
"Point of impact holding ability" there is a mouthful and also a succinctness about that phrase. Kind of relates to the 2 functions of every scopesight. Presumably, once point of impact is established, the reticle is no longer moved by turret change. Most riflescopes don't change point of impact, do they? Unless really subjected to great physical impact. Airgun scopes are designed to take the extra impact or piston movement physics that most riflescopes aren't designed for.
Jeff Cooper was the early guru of tactical rifles with his Scout concept which was conceived in the 80s. These were not varmint barreled rifles built to make tight groups, but light barreled utility rifles serving many functions with field accuracy and precision as one goal, but not the primary goal. Cooper initially sought to revive the B&L, Kuharsky type W/E adjust base system with the no turret scope like the B&L Balvar from 40s & 50s. Ruggedess was the goal.
I guess if you used a 1pc mount on Picatinny rail, and zeroed your optic before "testing", you could fasten it to a paint shaker or other machine that might reproduce physical force impacts, but what does that prove? Maybe the S&B PM-II/III series or $12k Hensoldt is engineered to handle that stress; but probably not... NATO sniper rifles have to survive/function after being dropped from altitude, like a plane; maybe paratroop sniper has rifle dislodge his kit from mid-air? Think that's gonna change point of impact?
While your offer to receive my $2000 merchandise for "testing" is "magnanimous". It seems pretty obvious you have no background in scopesight design, optical engineering, or quality control & product evaluation; no offense. Point of my comment about individual eyesight was to acknowledge the real elephant in the room when comes to optics; they're only as "good" as your vision allows.
I suspect "point of impact holding ability" is really small potatoes in the realm of scope evaluation. Any scopesight that won't hold zero is either broken or defective. Reticle adjustment repeats along with accuracy of each click value is really the foremost concern for a scope-sight used at varying distances. Of course, precision and tactical shooters are now concerned with needle-threading precision and over rate the need for "great glass" .
What a scopesight "does" is reduce the rifle sighting process from aligning 2 elements on different planes (front & rear iron sights) to a single plane with single sight focal point, the reticle. Cooper could not intrerest any mfr in reviving the non-W/E adjustable optic in adjustable base concept. Seems that is the most durable mode for scopesight use, because the optic is an isolated element and the W/E adjustment system can be super robust. The Micrometer adjustable rear sights by Warner and other quality highpower iron sight makers are noted for superb precision capability and repeat functions.
If one is comfortable using a hashmark reticle for holdovers and windage holdoffs then they could setup their scope, using a boresighter-collimator so that the hashmarks provide aiming points from 50 to 1000yds. With a shimmed scope base and something like the US Optics windage adjustable tactical rings, yoiu wouldn't need turret functions at all. Again, for those who want to do holdover/holdoff.
Ultimately, the last syllable of scopesight is the critical function, unless you are looking to put bullets through button thread holes at 1000yds.
Scopesights, due to all their integral components, and complex design features these days are liable to break or depart from design spec. I understand that Marine division level support have S&B technicians to maintain their scopesights. How practical is that if the supply/logistic support goes down? Shouldn't the military specify gear that don't need to be maintained by factory techs? It's not that kind of a world anymore...
