In NZ the range of brands would be similar as is the range calibres already mentioned,to which I would add Tika in brands & 25-06, 7mm Mauser, 7mm-08 & 270 Winchester in calibres. A lot of guys still shoot the 303 as a bush rifle though I think its more a nostalgia thing. Synthetic stocks & stainless actions & barrels have taken over the Gun Racks the last decade or so.
