A 7mm Mag full length sizer die will give you about .004 body clerance on the 7stw case. If you set the die high, it will only size the neck. Drop it down a little more and it will also touch the shoulder if that's something you want to do.
After 2 firings my 7mag die just touches the case down by the belt but doesn't really size it. It's set to touch the shoulder should they happen to grow but that hasn't been the case so far, so all I'm really doing is sizing the neck.
