I would choose the one that delivers the flattest trajectory with the bullet having the greatest sectional density. (Given adequate accuracy, of course!) Perhaps this would be the .340 WM, I suspect! Unless you could handle the .338/.378 Weatherby!

In the high country of Colorado and New Mexico, I have found the 7mm Rem. Mag., firing a 175-grain Nosler Partition at 3070 FPS, is all I need. But I don't take 400+ yard shots either any more!

When I think high country, I think of a lightweight setup....and in the .300 wsm that's a great combo.

My 2 elk rifles however are a .300 win mag, purchased before the WSM's came out, and a .340wby, my newer ultimate elk rifle.....neither is light....both almost identical and my .340 I would argue kicks less, but it does have a pachayr pad on it.

I think all 4 options you have chose are great options, anyone of them would work and do the job perfectly. Both are quality rifles in great calibers. In griz country though I think a .338 is a better option than a .300

My vote is for either rifle in .338 or .340....

.340 Wby. Mag. Good luck.

For me, 340 Weatherby, hands down.
For you, I have no idea.

.270 through the lungs no problems pick a good bullet and be done with it. if you want an excuse to get a new gun go for it just remember you have to carry the gun in and your elk and rifle out.
