Buying Whisper dies and 221 brass

[yulie22]

Howdy all. I live in Australia and need 300 whisper dies and 221 brass. Can anyone help out? None of the local shops stock dies, they are too specialised. Is there a reputable business that has a web site/on-line shop that I can purchase these items on-line easily. I searched Midway for 300 w and for 300/221 dies and can't find them. Also, is there a brand preference for 221 brass? I will be using my pistol for IHMSA if that helps. Cheers, Yulie.
