I know starline makes brass, and sometimes the ammo pops up in the exchange. It's pretty expensive though. If you get into loading it, hornady makes a good A-Max bullet you can use.
In Canada, only as a reloaded commodity. Buffalo Arms (US) has brass, and WAS sending it here, but I don't know if that's changed in the last few months.
In the good ol' U.S. of A hornady makes it and a "Coles Distributing" had some current production stuff available from a Yugo manufacturer.
Maybe some will magically appear here
