RE: Zeiss
oldelkhunter, I am well aware of the proper way to mount a scope. This scope was mounted in a set of Talley Rings and Bases. When I took the scope off the rifle, there were ZERO ring marks whatsoever. I don' t think there was a problem with mounting the scope.
I only posted this to say that all brands of scopes will have a certain percentage of failure. I just happened to be the lucky guy that got a defective Leupold.
