Well, you can scratch the KS off your list since it only comes in long action and only in ADL, plus if you can still order one from McMillan I think they up charge you an additional $100 plus I think they need 10 to even get the KS mold back in production. Its a great stock but not sure the fore-end has enough width to hold a #3 contour - maybe it could depending on barrel maker but probably not. But again no short actions.
The Mtn could work, I had a friend that had a #3 Bartlein in a Mtn rifle stock but it kind of looked funky - the fore-end just isn't enough to hold that big a contour.
Hunters Edge - sure thing that will work just fine for all your needs, makes for a great stock on a all out hunting rig.
Or like Cahunter805 said take a look at the Classic Edge which is maybe my favorite especially with a #3 contour barrel. So you wanted pics - 1st one is a KS.
Classic Edge with a #2b Bartlein which is about like others #3 contour.
Classic Edge with a #3 Lilja contour.
Not a great picture but the middle rifle is a Bart 2b, left rifle has a Brux #3 contour, both in a Classic Edge. IMHO the Classic Edge with a #3 is perfect
