Stopped at Cabela's in Sydney, NE last weekend to compare Burris and Leupold side by side. Afraid I'm going to go with the Leupold as they were much sharper and brighter to my eye. But the question is which one? Here's my set-up: Savage 10p Tactical .308 in a Choate Varmint stock. Going to limit myself to 600 yards for deer but the occasional coyote, rockchuck and prairie dog will also find themselves in the crosshairs. How much magnification is really needed for precision at this distance? Considering the MK4 in 16x, the Target in 24x or the Vari-X III in 6-20 or the 8-25X? What do you guys suggest? Many thanks.
