The only "all Aussie copper bullet" I use in my 7x57 would a 160gn Woodleigh Protected Point. The lightest they make those is 140gn, which I haven't tried. I have the Woodleigh reloading book and there's no mention of a 120gn bullet for the 7x57. It could be a Taipan bullet, but I don't know of any other Aus made bullets they could be talking about. Are they solid copper or jacketed?
