I see no reason to use a given (100 yard) zero, which is much too close of a zero and handicaps quick shots past 200. If I am going for a set zero, on most of my guns I will set it at 200 knowing I am only a little high at any range much past 25yds. Most scopes (with turrets) can be adjusted to any zero you are comfortable with and I personally ascribed to a Point Blank Range zero for most of my rifles. I know the zero and I know the max distance I can shoot with little time or thought. If I have the time I can dial it in to zero at any distance. In capped turrets I am not a fan of busy reticles; the Shepard, Leopold B&C, Leopold Wind-Plex, or mil-dot are all good IMO, but the Horus and others with a lot of marks are just too busy for hunting IMO.
