If a fixed power, certainly no more than 4x.
The 2.5x8 VXIII is great but maybe a little more bulk than you need depending on what the specifics of your "250 yard and closer" deer hunting. If you sit on stand in the gray light of morning or evening, AND you do some still hunting in the daylight - that 2.5x8 is perfect. If all you do is still hunting in the woods, I'd just get a M8 4x33 or a 2.5x compact. (or the newer FX-II versions of either of those).
Of course no need for any Gucci reticle to shoot under 250 yards.

Have fun,
