Don't stress out, guys. You can have your zero stops and full adjustment on your favorite Zeiss scopes. I'll show you how. :-) Look at the picture.
You guys can make your own "zero stop" by fitting a washer (shim) under the elevation turret itself. I look at the picture of the Zeiss HD5 turret. Turning the turret to the Left moves the point of impact "down" and the turret itself moves down toward the base of the scope.
First set your zero. Then grind the washer to the right thickness to "stop" the turret from moving further than your zero, thus making a "zero" stop. Then you can enjoy your beloved Zeiss optics and its full adjustment range.
I have done this with my Sightron SIII. It has similar turret design. I use nylon to make my washer because it is easy to grind, paint, and mark. Just find the right washer diameter for the turret stanchion then grind, grind, and grind. Enjoy.
