OP didn't state whether his/her Z5 had the BT Turret, but I will forward this tidbit.
When making elevation adjustments on a Swarovski scope (Z3. Z5, and Z6) with the BT Turret, do yourself a favor and use the include "BT tool". You'll save yourself a lot of headaches and ammo. I've run into a number of folk that have neglected the use of the BT tool, and unknowingly run up against the zero-stop when making adjustments. Guilty of this myself.
