Though I don't know for sure, it's entirely possible that today's Alliant 2400 isn't exactly the same as the old Hercules 2400.
Alliant has data online: http://www.alliantpowder.com/reloaders/RecipeList.aspx?gtypeid=1
I can't say your old data isn't still valid, but it's worth a sanity check against modern data just to be on the safe side.
Somewhere in the reloading area here is a thread dedicated to online data sources.
All of my loading manuals are about 50 years old and, while I still consult them, that is just where I start when working up a load. I use the online data offered by the manufacturers and stay away from what I see in some online sources were Willie Lump-Lump says this is the best he ever used. I do use some data from people I have known for decades who are sane, stable reloaders I trust, but I always check their data against the manuals and the manufacturer's data before I decide on a load I want to use. I have two friends I trust when it comes to load data, both love H110 for .44 Mag.
