I was looking for scope with hold over capabilies when I got the 270wsm. I look through Leupold,Sheperd,Nikon and Burris. To each their own but I liked the Burris Ballistic Plex. I got the Burris Euro-Diamond 2.5x10x44mm objective with the Ballistic Plex retical.I sighted the normal crosshair at 200yds. with factory Winchester 150gr. Power Point ammo. I am within plus or minus 2" up to 600yds. with the given range that match the retical. 6" difference at 600yds. Which I will never shoot past that point with this set-up. I am currently hitting consitently 6" dia rocks at lasered500yds. off the bypod kneeling. In my eyes that is good enough to put a round into the boiler room off a deer or elk.
