Belted or short

Whatever you can group in the vitals, from field positions, at whatever range you intend to shoot at and carries enough terminal energy to do the job is the cartridge to choose.
Also, why 270 WSM? Even at 400 yards, using the same bullet, the difference between 270WSM and 270 Win is about 1" when they are both zeroed at 100 yards (as an example)
If my max distance is 600 yards (not saying it's right, just what happens in the mountains of Europe and especially NZ) you are going to need something that is carrying over 1000ftlb of energy as a minimum at that distance and expands reliably at the bullets TV - whatever that may be.
First find a rifle that you are comfortable carrying uphill and down dale, then find the caliber that suits quarry and expected range
Having hunted in mountainous regions frequently I don't understand the need for a light rifle. Maybe that comes from having done much mountaineering as a youngster with heavy packs on. My preference is for a heavier rifle that I will be confident with to take a longer shot if required. The one thing I would change about my current 'mountain' rifle is the barrel length, I would have it at 24 inch not 26.

I used .270 for years for chamois, and a shorter ,medium weight barrel and open sights are a must IMHO. Even the most robust rig can easy be knocked off zero if you slip on some boulders... My playground is between 6000 - 8200 ft above sea level and takes a whole day to get where the action is, so you want your kit to be in good order, going back is not an option...
Below is a pic of my playground,taken last year, so you'll have an idea...![]()

Pretty. Mine runs 4-8K (I live at 3.5K) and along with the rifle, you need to carry gear to keep you alive should you run into difficulties. A light weight rifle is a real benefit.~Muir

Hmm, I'm 19 and spend my whole life working outdoors, stalking, walking, running marathons ect. I'm not trying to brag just show that I'm pretty fit and used to hard work. However two days in to my recent nz tahr hunting trip I decided I hate heavy rifles, so much so that I'm now getting a new t3 lite .i can't understand why anyone would burden themselves on such a hunt with a heavier rifle.
