Which model of Zeiss?
The 6.5x20x50 has 45" of elev. @ 100 or 450" at 1000
The 4.5x14x50 has 68" of elev. @ 100 or 680" @ 1000
The other models I'd have to look up.
You'll most likely need taperd bases or Burris Sig. rings to get the most out of your rig. I've got one that took .015 worth of inserts in the Burris rings to leave me 37 moa come ups, another took .040 of inserts in Burris rings PLUS a 20 moa tapered base to get me 42 moa in come ups.
So many variables, ring spaceing, reciever truness, bases accuracy, you just can't be sure untill you get set up.
