I used several for 30-06, 30-30, and 41 mag. But - I slowly beat up the case bases. For a cartridge like the 223 I'd recommend you wait a little, save up and get a Lee press,or one of the economy RCBS or Lyman presses. Note - Lee has a "Surplus" section on their web site and you can sometimes get factory seconds, or factory refurbished gear for very good prices. I've nabbed a few bullet molds this way. I don't know how the Australian Ebay is but I see a LOT of economical presses on Ebay. I'd look for an RCBS Jr or similar.
Also - I highly recommend some sort of a powder scale - I think it will assure more consistency and safety in your loads. In addition it lets you explore a wider range of powders.
Have fun!
