I have used the VX-2 1-4X20 on a .44 mag rifle and a .308 carbine. On 1-power, the field of view is tremendous and aids with shots where deer are moving through the brush, and the 4 power would help with the longer-shot scenario you speak of, though I'd probably still use the lower power for that. Nonetheless, the extra magnification would be available.
2-7X33 is nice, also, but I prefer the 1-4X20.
