About changing the bolt face, it's a lot easier to open up the bolt face to a larger diameter than go the other way. Even here in Denver I don't believe I could find a smith to close up the bolt face on my Browning for a reasonable price. The smiths that I met have more profitable projects to do.
So think $$$$.
Also, there is going to be a problem trying to get your Browning WSM magazine to feed SAUM. The SAUM is 0.20 shorter. This is enough to cause a problem feeding. The magazine will require some remodeling. It helps if you have done this before. Unless you can afford to throw $$ at magazines for experimenting, you would be better advised to stick with a WSM cartridge for your WSM magazine and WSM bolt face.
I have jumped through these hoops to get my 7mm SAUM Browning to feed and function as a repeater. Next time I will choose my cartridge from the magazines that are available from Browning.
You might be able to sell this rifle and buy something easier to customize.
If you choose to build on a Remmy, Winny, or Savage you will not have this problem.
Hope this helps.
