The Leupold FX-3 6x42mm Adj. Obj. Competition Hunter seems to have everything you want. Fine crosshair with 1/2MOA dot, target turrets and AO. I haven't gotten my hands on the new FX3 yet, but the old/current FX111 is one sweet 6X scope. These have improved lens coatings and the Mark 4 erector assembly springs.
These scopes were built with Hunter Benchrest in mind, which explains the target features in a comparatively low powered scope.
