Z3's don't hold zero's well. Z5 2.4-12x50 with BRH preferrably. There is no other choice that comes close IMO - unless you have to dial or have illumination. (although they make such a version but mixed opinions on dialing results) Excellent optics, light and small and super reliable....
I’ve been leaning towards this
.... I’ve also been considering same scope with a standard reticle and getting the custom elevation turret
Custom elevation turret is nice, but the BT that is available on multiple models works very well. The key to any elevation dial or ballistic turret is accurate data input.
FWIW, and if you se the need, Swarovski introduced illuminated reticles in the Z5 series for 2020.
