If you insist on domed headed screws, dress them down to a very gentle dome...not the factory lump. Especially on butt plate screws, nothing turns me off (when it comes to screw heads) like a gobby fat round headed screw head sticking up out of a butt plate. I usually file buttplate screws flush with the buttplate, the slot on the same plane as the bore. Patchbox screws are the exception...I still like a modest dome, but filed flat works too. Escutcheon, and other inlays' screw heads - flush and flat. My preferences, of course.
