Hodgdon's Reloading Center has data for the 180 in the 300 WSM.
I haven't shot the 150 in the WSM but the 180 is pretty good. I just bought a box of .284 150's for my 7mm's and can't wait to shoot them.
I haven't gotten one bloody yet, but a little searching will show they are excellent for Deer, Elk, Moose, Etc....
