RE: Zeiss vs Leupold
I too like standard heavy reticles on my big game setups, I once had a ballistic style reticle on my 270 and while i liked in practice or varmit hunting in the some times fast acquire of deer hunting it was a royal pain in the arse to me.
As for which scope after much comparisons and research I choose the Zeiss Conquest. The constant eye relief, 1-piece tube design, etched reticle, NA warranty (which in my research has been getting rave reviews), quality through and through were some reasons. After mounting the Zeiss was impressed at clarity, brightness and light gathering when I could really see how it faired in the real world. Something I consider a good indicator is the tracking of a scope upon adjustments the Zeiss is bang on (I will say my leupold have been great in this area as well). I guess you can say I was impressed, so much so I bought my second Conquest a couple months later.
