Please help with reloading data question?

I have an unopened pound can of Hodgdon H 450 powder. I am having problems finding reload data for this powder. It is my understanding that it was discontinued some years back. Several people have told me that this is an excellent powder for medium cartridges. I am reloading for a 30-06 and .257 Rob. I have been using IMR 4350 for both of these. Any help on where I can find this data would be appreciated.
