Double and triple check it before your hunt. I had a nib Ziess 4.5-14 Z800 last year that was defective . It would zero out just fine on my Sendero 25-06. I swapped it over to another rifle with same mounts and not enough windage. Naturally I thought something was up with the rifle as gneiss mounts and scope had proven good on another. So I swapped it to yet a different rifle and same problem. Put it back on the Sendero dead nuts zero. So I started doing some tracking tests with the scope. Ziess reports 60" windage @100yds. Mine had 19". Luckily the Sendero was d&t perfectly so not much adjustment was needed.
I do hope for you it is the mounts because Ziess customer service leaves much to be desired. They did send me a new scope but it took about 6 moths and several heated phone calls to get it.
