Bolt face question

[PBking51]

I am looking at building either a 338 rcm (most likely) or maybe a 6.5prc on a model 7 action. The bolt face for the action was for a 300 wsm. Are the 2 case rims close enough that it'll be a matter of slapping a barrel for the new cartridge on it and headspacing or with the bolt face have to be altered? I realize that there will be more work to do, but just focusing on the bolt face at the moment.

So I've got a face of .535 and rcm is .532 according to saami.

Is that close enough?

 

[DaveTooley]

It will work.

Lastly. I can use the same extractor too?

 

[DaveTooley]
