Dunno, its a fairly new powder released by Hogdgon. In general most new powders seem to claim they are more temp stable .... whether that true or marketing BS who knows. But in NZ conditions I doubt there's enough temp variation to really worry too much about.
99% of time NZ will be 15C +/- 10C. I guess if you're chasing Tahr mid winter in extreme weather then thats a bit different. Even then I'd be keep the ammo in my pocket anyways.
