I have a 7SAUM and a 7RM. (*and a 7x57 for what it's worth.)
The real difference between any of them is brass and loaded ammo availability in foreign countries.
In other words there's no appreciable difference in the USA between the WSM, SAUM and RMag for any hunting purpose. Ammo travels with the rifle in the USA - so for any domestic hunting either round is fully acceptable.
I drilled a mountain goat with a 140gr. AB bullet at 3050 fps. It died.
I also dropped Beest (*all three), Zebra and Eland with a 150 E-Tip at 2950. They all died as well.
If you want to hunt Africa...or other countries, ammo availability has a valuable benefit.
Otherwise, a 7mm driven at decent velocity will do the trick.
The designate of WSM, SAUM, RM, RUM STW or otherwise matters little. It's just a question of impact velocity at a certain distance.
