What I've seen on the round is that it more finely splits the hair between the 30-06 and 300 magnums.
The 300WSM sits on the 300 Winchester Magnum side of the fence between the 30-06 and 300 Win Mag...in other words, it doesn't quite reach the 300WM's capabilities, but it's closer to the 300WM than it is to the 30-06, if that makes sense.
What I've seen of the SAUM is that it's a bit closer to the 30-06 than the 300WSM is. So, not QUITE able to run to the same potential as the 300WSM, which means there's a little more daylight between the SAUM and the Win Mag and a little less between the SAUM and the 30-06.
I wouldn't even consider owning one if I wasn't a reloader. Even the 300WSM is tough on the wallet, and tough to get the performance you'd want, if you're not handloading for it. If I wanted to run factory and have a 300 mag, it'd be a Win Mag, hands down. Nothing else would be competitive for buying "off the shelf" food for it.
Of the non Win Mag options, on flat out performance, the 300SAUM, 300WSM, and 300H&H are all packed fairly close. Flip a coin, take your pick. You'll get more than a 30-06 but less than a 300WM. I have the H&H and WSM versions. I run 180gr Nosler Partitions out the muzzle at 3000fps, +/- about 25fps depending on which one and which load. A 300WM can touch 3100 from what I've seen for the same bullet. A 30-06, IIRC, will redline somewhere around 2700-2800, roughly.
Again, if you're not running a loading press, I'd have it rechambered... of course, if it's a short-action, your options are severely limited, and not to anything that's substantially better for factory shooters.
