I am trying to fit 5" crown molding (38 degree spring angle) around an
outside bullnose. I've been trying to use a compound miter saw to cut
at 22.5 degrees but have been doing something wrong because I end up
with too small of an angle when I stick the three pieces together.

22.5 will be correct. Turn your crown upside down on the saw with the
flat part on the back of the bottom edge (the part that would go
against the wall) flat against the upright fence on your miter saw.
No need to use the compound feature if your saw will cut through the
molding sitting at that angle on the saw.
You will need to hang past the radius just a little coming from each
direction to make the pie piece work. The first one is the hardest
but you'll get a feel for it.
