pro's: It's a mil based reticle, easier to range with then mildots(especially beginners), more precise hold over/hold off reference points(especially beginners), hollowed center cross doesn't cover target.
con's:If you're getting one installed it probably means your reticle and turret adjustments won't match, but that has been the case for many-many years and has worked to this point(shooter preference).
I personally prefer it (or similar) over dots or a generic drop reticle like the VH I have in one scope.
