Xmanpike;
I hunt with a .338 Winchester magnum bolt gun myself. It's my dedicated moose, bear, elk gun. It wears a Zeiss Conquest 3.5-10X mil-dot. And that's one helluva piece of glass.
I, personally, far prefer the mil-dot reticle system to any of the various BDC systems. I happen to have a Nikon 4-12X with their BDC, and it'll get replaced with a mil-dot at sometime in the relatively near future. As you may have noticed, I'm in Montana, on the front range of the Rockies. The wind blows here. A BDC does not give you a reference point for windage, mil-dot does. It makes a huge difference in field usability, believe me.
On another note, the Leupold VXIII is not their current line. The present scope is the VX-3, and it is superior to the older VXIII line. However, you owe it to yourself to investigate the Zeiss glass. I do believe that within your budget you'll find some very satisfactory glass from Zeiss, with lifetime warranty also.
