I think my Duralyt has 'hit the wall', that is after I recently loosened the scope rings to slightly pull back the scope objective lens closer to my eye on account of having to crane my head to far forward, I have tried to re-zero only to find that it would not have enough adjustment left on the horizontal to pull it back on zero leaving it two inches wide to the right. I guess this means getting the scope remounted and centred with a collimator centering the crosshair and all adjustments? Before re-zeroing yet again? I have really liked this scope in so many ways, so I would still vouch for it, but this is annoying. Have you experienced this out there or on other scopes? Maybe the original mounting was not spot on and did not help matters?
