Never heard of them, had to look them up. Appears they are sold in Australia (hence the name). So, unless you are in Australia, why worry about a bullet you may never see? But just to stir things up a bit, their site says they are solid copper, like Barnes X or Hornady GMX bullets (let alone that Hornady has NEVER used solid copper because of fouling problems with solid copper). They are grooved like Barnes TSX bullets to reduce fouling. If you want a solid bullet, why not try one of the local brands?
