In all honesty I stopped buying reloading manuals. Nowadays I cross reference Hodgdon, Nosler, Speer, and /or Alliant all of which offers online data free. I'll still go to my old manuals occasionally if needed.
I like quickload .there is a learning curve , and it's an investment but I feel it's worth it .
usually I can make do with my older books by picking a similar bullet as to what I'm loading . if you're loading something such as mono metal , long slick VLD's , a boutique bullet , I would recommend buy that bullet makers book .
The manuals are fine for reading about reloading, but for data, it is hard to beat QL. To stay current, it does require the purchase of the update each year. However, the cost of the update is nominal for the data delivered.
Given Australian Defence Industries produces a number of the Hodgson powders, for those using those powders particular, then this is a good source. If you're not familiar with the OEM names for powders, there is an equivalent chart under Powders => Powered Equivalents
