You may want to check out Buffalo Arms (www.buffaloarms.com). They show that they have die sets for both 8x56 M-S and 9.5x57 M-S in stock. 8x56 M-S is $86.87, brand is 4D; 9.5x57 M-S is $86.87 for 4D and $145.66 for RCBS.
They show brass in stock 8x56 $1.47 per case and 9.5x57 is $1.91 per case. The more you buy the cost per case goes down.
No .325 bullets; they have the usual suspects: .323, .327, and .329.
They do ship to Aus and N.z.

I have bought dies and loaded ammo for 8x56 M-S from them, worked great.
