For those interested, ADI advertise their military products under their 'Australian Munitions' trading name and even identify the propellant powders used.
AR2205 seems to be used only in 81mm mortar (page 21), no faster pistol powders seem to be in use so it is unlikely that they will divert any existing plant capacity from slow to fast powder production.

It does seem likely that 2205 is currently being produced for military contracts but with no spare capacity to feed any into the retail market.
