Mil Dot reticles take some practice to use properly, but once learned the process is easy to employ. For hunting, its probably just as practical - and often quicker- to drag along a good laser rangefinder. The rangefinding reticle is a good backup, however, in case you have problems with the laser.
Check out the Leupold VariXIII and Tactical series scopes, for a 338 the 3.5-10x or 4.5-14x make sense.
Shepard, Nightforce and Trijicon also make an excellent line of quality rangefinding scopes, some with illuminated reticles for low light hunting, and of course Swarovski and Zeiss glass is considered top notch.
Why would you ever be in a lowlight situation, what with your spotlight on the deer and all?
