Bob,
I hunt in open desert country that is often times choked with sage brush and the like. My longest shot ever was just over 100 yards. I took an Aimpoint off of my AR and replaced it with a 1-4 Leupold. I haven't used it hunting yet, but I sure like the fast target acquisition of the lower power scope. The Aimpoint was nice, but difficult to use in low light (for me anyway).
In the country I hunt in, I'd rather use an under powered scope than an over powered scope.
4X should be fine to 200+ yards and I don't plan on shooting them that far out anyway.
JMO.
Mark
