I have a Leupold 4-12x on my .243. The primary use is woodchucks and other critters, but I also wanted to use the rifle as a back-up for deer. If I did not want to be able to use for deer season, I would have went with the 6-18x scope. While it is true that higher magnification will increase your wobble, I find myself shooting off a bi-pod 75% of the time when shooting chucks, crows, etc., so it does not bother me.
