The only updates I could imagine them adding would be data for a few newer powders like BE-86, CFE Pistol, Superformance, Leverevolution, the new IMR powders, and LT-32. And Hodgdon, Alliant, and Accurate have already released data for just about everything that those powders are probably useful for. If they do come out with a 50th anytime soon itd be nice if they added data for some of the lesser known powders that have recently been imported, like the Nobel Sport/Vectan, Lovex, and Norma powders. You can find data for those but its pretty limited. Most of the Vectan stuff has old data floating around, but who knows if the formula has changed since then.
