[SakoShooter]

While the only scope I have had die was a cheapo that I was lucky to get a year out of...that doesn't mean decent scopes can't bite the bullet (hah) as well.

In my instance, rifle was no longer zeroed....tried to re-zero....couldn't as the reticle seemed to adjust with a mind of it's own....bought a better scope. As I recall, I didn't really try to group with it, it was out of zero and I couldn't get it back to zero.

I'm guessing that Zeiss will stand behind the scope you have, I would check that everything is mounted securely, and try to re-zero at 50 yards or so. If it's doesn't track adjustments as it should, you know for certain that the scope is broken and you can contact the Zeiss warranty department.
