I chanced on this old thread and the Mc name popped up,interesting as to his thoughts on fluting.

Contrary to genral impressions Stainless steel that is used in the
firearms is not more difficult but is much more machineable than
chromoly. The s/s used in barrel steel is stainless screw stock 416R made
to run on auto screw machines at high speed. The steel used in s/s
actions is 1704, a tougher steel that take more tool pressure but
machines nicely. Stainless doesn't have the tensile strength that a
chromoly like 4340 does. Due to the softness of barrel s/s which is 27
to 29 Rockwell C it will not last as long as 4140 and while it is
believed to withstand heat erosion better I have not found that to be
true. As a summery due the better machine ability, s/s barrels can be
made with closer dimensions and surface finishes. It will produce more
accurate barrels. The sole benefit of fluted barrels is that to some
people it looks neat. If you are lucky a fluted barrel will shoot as
well as or nearly as well as an unfluted barrel. And the gunsmith needs
the money.
