Need help with W780 Supreme.

Does anyone have any data for this powder with the .257 Wby?

It's right next to H4831 on the burn chart from Hodgdon but would take any input.

Thanks

There seems to be no data available from the joint Hodgdon/ Winchester/IMR data center.

All I could find was the following,

Yeah, that's all I could find too. I just wondered if anyone has used it and what they were using as references or had generated any data for themselves.
