Anyone load any 270WSM with the Hornady superformance powder? Looking for a starting point being I have a jug of it. There’s data for 300wsm but not the 270WSM. Was wondering if I could take the 300wsm info and scale it down based on H20 capacity vs recommended load? Find the ratio for the 300wsm and apply it to the 270WSM?

I would call Hodgdon and ask. They list it for 243 wssm, 25 wssm, and 300 wsm. There's likely a reason for no data for 270 wsm but they will know. Likely it's they wrong burn rate.
