Blue Dot can be used if you find the data. ZIP will only work for standard pressure .45 COLT loads. So it's not a good choice for hunting loads. In the last few years I have been using Ramshot Enforcer for my Magnum revolver loads. There is very good data for a 30,000 PSI Ruger/TC only handload using the deadly Barnes solid copper XPB 225 gr. JHP to around 1500 FPS at Ramshot
Like Sr40ken said, you'll also find data at the Alliant, Hodgdon (Hodgdon, Winchester, IMR), Accurate websites as well.
Are you shooting .44 Magnum or .45 COLT?
