What you describe here is the right way to reproject WMS layers, and the
fact that you see a small rotation effect in the WMS layers when you
switch projections confirms that MapServer in indeed trying to reproject it.

The only thing I could think of is that perhaps your shapefile is not in
the projection you think it is. Maybe a different datum, or something
like that?
