Broz,
Really hard to go past the NF for ELR if you're an MOA kind of guy, which we are too. I can visualize feet and inches at any range but mils??? ***???
Optically the Swaro Z6's are arguably the best, but they make no serious long range scopes. Same for Zeiss, some nice optics and some tactical models, but not enough up. The March's are awesome, and I love my 2.5-25x42 as Augustus says. Its a superb all round hunting scope and it works really well on our lightest weight long range hunting rifles, but that 42mm objective is definitely marginal if you want to still be able to use a fair bit of magnification in low light. I use 20x max most of the time with the March, and in low light that I could still run 20x with the 56mm scopes, have to come way down to 10 or 12x. The bigger March's are superb, but only 60 MOA up which is marginal for ELR. They have all proved to be indestructible though, even on our 8lb all up 338 Thor's shooting the 300gns at 3100fps with rearward angled brakes. That combo shakes most scopes loose sooner or later, but the baby March's are still going strong! The S&B's are good, but overpriced and dials go the wrong way for me. Too confusing in a hurry unless you run only European scopes. The top Leupy's are nice for lightweight, good enough optics and superb warranty, but not really the best choice for big gun recoil at ELR. We have had a couple of Mk4's shake loose on the big guns. IOR's have some of the same issues, arguably without the same service.
So that leaves NF's. The only issue we've had with our NF's is one that had its parallax and focus out of kilter at long range. You couldn't get the sharpest focus and the parallax out at the same time. NF fixed it no problem. And like Jeff, we always found NF's to be about the only scope whose adjustments religiously turned out to be true MOA - that is until one 8-32 NXS that seemed to shoot bullets flatter than everything else. On the test jig against the grid sure enough, it moved 1.071" instead of 1.047". Until then, we'd almost got to the point we didn't bother to calibrate the NXS's, but now we calibrate everything. You have to be sure and even NF has the odd hiccup.
I agree with the 5.5-22x56 for its extra up. We run a few 8-32's as well, and seem to use them mostly on 22x as the range gets long anyway! Rarely are the ambient conditions good enough to use much more, and we've hardly ever felt 22x wasn't enough. And certainly get the zero stop and don't use winding to the bottom and then back up to find your zero as someone said. Stay away from the extremes of your adjustments and don't hit the ends or you do risk a POI shift.
That's our experience for what its worth!
