another model you may look into is the winchester model 70 extreme weather stainless, though i'm not certain if it is availabe in .300 WSM. bell and carlson stock, free floated, stainless fluted barrel, it is a mighty nice rifle and one that i intend to purchase in 30-06.
It does come in .300 WSM. I have it in .30-06. I highly recommend it.
It's light, but not ULTRAlight. I put Talley lightweight one-piece ring/mounts and a 2-7x33mm VX-II on mine, and it's a nice, light package that shaved at least a pound and a half off the rig it replaced. However, some of the Titanium guns could be done up to be yet again a pound lighter, I think. Depends what you want, and what it's worth to you.
I'd consider the Kimber, probably not the others, and I'd look at some other things. The others are push-feed rifles. A higher-end rifle to be used on foot in serious terrain ought to at least have a serious action, and to me, that means CRF. There's something to be said for "3 Rings of Steel"
in a Mark V in some fun plinking caliber like .338-378, but for the most part, CRF is a design meant for real field use, not just the simplest and cheapest one to make without screwing up.
Tikka has done quite admirably, for a cheap gun, but the T3 Lite is not in the same class as the rifles the OP listed, so I have to assume that's not what he's looking for. A Remington doesn't even have a bolt lock; IMO Remington doesn't make
any rifles I'd want for hunting on foot, out of the box. It's gotten hard for me to take them seriously.
For the money any of the Titanium rifles cost, there could be some interesting options out there.
