Does anyone know the volume measure density of Winchester Sta Ball Match?

Not seen an official number and Lee hasn't updated their charts yet.

A non-labgrade measurement with a 1cc dipper and beam scale showed a 14.5 grain average weight for 3 samples for me. The jug had a 54.9% humidty reading from the Govee sensor I have in it.
