the problem is, that the file get's the primary group from root!!! - so 
if u use 0XX0 permission, other people have no access to the files.

give the directory the right group and use the gid bit.
e.g.:
directory: rights: 2770 / owner: somebody.win

in smb.conf:
directory mode=2770
create mode=0660

so everybody of the group "win" has access to the data. even if "root" 
creates a file..
