Another one to look at is the 7mm Rem. mag improved or better yet the 7mm Weatherby mag. The Weatherby will work in your action length and has a very good neck and shoulder design allowing it to handle big heavy bullets better
There are a lot more wsm shooters than saum..so saying they are better for barrel life and accuracy would be up in the air as far as I am concerned. I don't put a whole lot of extra time in what other people say about brass design, if that were true magnums should never shoot, specially with that nasty belt. Furthermore a 7 Rem mag handles heavy bullets just fine..

What's wrong with the standard 7mm rem mag firing a 160 grain accubond or 168 grain Berger at around 3000 fps is good. If I had to go with one you choose it would have to be the 7mm WSM only due to the fact I love the WSM rounds. The 7mm ultra mag is impressive but I would jump up and fire the 300. Win mag or ultra mag at that point.

If only a choice of 270wsm vs 7mm wsm vs 7mm ultramag, and elk is the quarry, I would opt for the ultramag. Elk are big, and bullet placement on elk isn't always perfect, so the extra power helps some. For the other game, an ultramag is a bit much. Too much cost, barrel erosion, muzzle-blast & recoil for most to be comfortable with.

Between the .270 wsm & 7mm wsm, I would opt for the .270 only because the 7mm wsm has been dropped by Winchester and factory ammunition may be less available in a few years. Otherwise the differences are negligible.

A .270 wsm is a great all-round cartridge that will take any of these animals but I think you posed the wrong question. The right question in my mind would have been, "Do I choose one of these or jump to .30 cal?". If that question was posed, I would strongly recommend jumping to .300 Weatherby or .30 wsm because both handle heavier bullets than the .277 or .284 cartridges, and heavier bullets are a real advantage when the perfect shot doesn't present itself, or you don't succeed in making the perfect shot.
