OK, let's go with that. How do you find your recipes at this time for the loads you are going to load? From the internet forums?
I seriously hope not!
If you have a manual, what kind is it?
What do you do when you can't find data for a powder/caliber combination in a manual?
Here is my suggestion, go to the powder manufacturer's data website; here:

Guess what? They have the data you are looking for!
