I use 150gr E-Tip in a 30-06 it's one of my cow elk rifle and I've played around with the 168gr E-Tip in a 300WSM along with the 165grTSX,168grTSX and 165gr AB.
In the box of E-Tip I got the rec .050" to .100" of the lands for optimal accuracy and not to exceed mid load. Alliant site has loading data for the 300WSM using 150gr with R-17. Nolser manual #7 they have load for the 300WSM with 150gr E-Tip and they give special seating depth with E-Tip and none of the loads use R-17.
Alliant site does have loading data or the 300WSM using R-17 and 150gr bullet but it's not the E-Tip. I think you should call Alliant and get a start load from them be a good place to start.
