350 WSM is the 350 Sambar, might want to look it up.

I considered re-chambering my Ruger 350 rem mag to a 350 WSM, but then I shot it pushing 225's 2700 fps. I just have no need to push 250's 2700 fps from a lightish rifle. Something to consider. And if you aren't building a light rifle, no real reason to use the WSM platform.
