I just finished a 7mm SAUM on a Savage 11 action. It turned out pretty nice. However, there are a few things to note.
First, unless your action is already a shortmag action you will need to change the magazine box and the bolt head, the bolt head needed for a WSM is a control feed type instead of a push feed.
Second, Savage has two different sized threads on their recievers(switched a few years ago), only the larger size is recomended for the shortmag chamberings.(smaller size can be used but I was advised against it) You will need to know which you have when ordering a barrel and recoil lug.
Third, if you are even thinking about shooting heavy for caliber bullets you might want to consider a long action( although feeding can become an issue). Seating the longer bullets so they are close to the lands usually eliminates the use of the short action magazine box because the rounds won't fit.
If you find yourself in need of some parts let me know, I've got some laying around I can sell.
Hope this helps.
