I have had the chokes on a few "field grade" non-collector SxS's opened up, and been very pleased with the results.  These are working shotguns that I FREQUENTLY USE for hunting, sporting clays, trap and skeet.
Most of the older SxS's left the factory choked F & F.  I have had the right barrel opened to IC.
This seems to me to be a good hunting combo - near and far.  I can still use the FULL barrel for trap, and the IC barrel for most skeet singles shots.  On the skeet doubles, I use the FULL barrel on the most distant shot.  Its a good compromise solution.
