Why make a nut for a Panda or BAT when you can headspace them (and even clock them for a Panda) with a shouldered barrel without having the action in hand? The only reason for a nut is sloppy tolerances on factory actions from receiver face to boltface.
I know that and you do too but we got full fledged rifle builders in business full time that dont even own a lathe or mill.
