In my experience, RDOs turn average shooters into great shooters and great shooters into phenomenal shooters. It is still an acquired skill that takes practice to master. For fast moving game, an RDO can't be beat. If you need magnification, use an additional 3x magnifier or a Trijicon ACOG. A 1x-8x scope or LPVO, low-power variable optic, especially with illuminated reticles, is the ticket. How much you want to see past 100 yards depends on how much you want to spend.
