I load using the same data for both and have for many, many years. The data difference you are seeing is most likely related to a manufacturer's bullet/powder. kind of like a marketing tool so as to say this is what works for this bullet/ powder so they can associate the two as a mated pair. But that is onyl my opinion based on hand loading the two.
