What bullet?

WSMs seem to like H4350, H4831, RL16, RL22, and MagPro. Magpro seems to be a moody powder when it comes to temp sensitivity but produced some really nice groups.

I bought a LB of mag pro and now not sure what I'm going to use to work up the new loads.

Accurate Powder's free data says Starting is 65.6 and max 72.9 (compressed)
Nosler's data says Starting 65.5 and max 69.5

Both have wildly different velocities with Nosler's being very generous. I'd start at min and work up in 1/2 grain increments because of how different the two loads are.
