I have found obtaining loading data on my 300 Norma a little scarce id you'd like to use any powder other than Norma proprietary powders, so I sat down with a beer and started reading through the Norma reloading manual and stumbled upon this chart, it doesn't list any of the Aussie ADi powder directly, but gives you a very good indication which powders contain similar property's.
This chart contains a little more detailed version of the information you see in the ADi reloading manual, but covers every Norma powder against the rest...
I hope it is useful to someone.
Cheers
Dan
