RL-22 is what I was using when loading WSMs. That was before RL-17 was released. I'm looking for a 7WSM soon, and will be trying RL-17 first...
I use 69g of IMR 4831 and Barnes 165g TSX bullets. In my 270 WSM I use MagPro and the Barnes 140g TSX
Handloading is a hunting process. Have fun finding the bullet, the powder, the powder charge, and even the primer your barrel likes. May your barrel be concerned about your billfold.
