The Kimber is a big step up from the other rifles you mentioned.
The short action .308 is a light weight rifle.
This year they are coming out with a stainless rifle in the long action calibers.
I know it is available in the 300wsm but don' t know about any other calibers which may be available.
If I had the cash I would buy one in a second. For the money either the lightweight or the stainless rifle would be quite a value.
