You can use the Hodgdon data. Don't sweat the difference between a 147 XTP and 147 LRN. Use that data, and if you want to be safe, use the data from the next heavier bullet weight. You'll be safe using any 124gr or 125gr data for a 115, for example.
This isn't nearly the problem I think you think it is.
Thanks! I ended up ordering some 125 gr TC Blue Bullets. Looking forward to loading those up.
