Keep in mind that the 'long action' Kimber 8400's are really a magnum action length with a spacer in the magazine and a shorter bolt stop.

Now you may want the longer, heavier rifle however I feel that the Kimber 8400's in the WSM cartridges are a standout rifle.

Consider a Kimber 8400 300 WSM. Its neat.

The Kimber in the 300 WM weighs 10 oz. more and is 3" longer than its WSM brother. Two inches of that extra length is from the 26" barrel that the long action 300 WM's come with!
