I don't own a Kimber but I've handled many and shot a few. In the handling area the fit and finishe is excellent. Of the ones I've fired the 7MM-08 was pleasant and the 300 WSM was not! Take a look at the weight of the rifle and you will see that the recoil will be harsh out of the 300 Win. Mag. I shoot a 338 Win. Mag. as an elk rifle but my primary rifle for deer and hogs is a 257 Roberts. As long as you can handle the recoil buy the Kimber in 300 WM, but do spend a little time thinking about the recoil from every shot.
