I looked at this review and maybe missed it, but was this scope mounted with the rings lapped? I personally have found that a scope that doesn't hold zero isn't necessarily always the scope. You have to look at the whole mounting system before just saying the scope is "junk". Most if not all of the problems, I have encountered have been remedied with lapping the rings, torque wrenching to proper specs, and locktite. I've found if the rings aren't lapped properly the consistently of pressure on the scope isn't held in a uniform manner by the ring, Because the pressure is isn't uniform across the scope, under recoil it tends to move. I believe this accounts for more point of impact change than anything.
I understand you get what we pay for and I'm not arguing that there is a better scope out there than the Nightforce. In my own testing the repeatability and reliability of every Nightforce scope I've worked with has been substantial. However, I never have had trouble with many Leupolds and Vortex scopes holding zero using the techniques stated above. Some have taken more work than others, but all the ones that I have mounted have held zero year after year even with hard use. Tracking and adjustment on these lower end scopes has been another story. If you plan on dialing, I would encourage everyone to shoot a vertical adjustment test because I've found a lot of discrepancy in adjustments stated by manufacture and what I've measured.
