In Australia, wildcat cartridges were relatively common. Most are made primarily for hunting species such as deer, kangaroo, are generally based on the .303 British because of the post war popularity of that round and of the cheap surplus Australian Lee–Enfield MkIII military rifles available. Many of these surplus rifles were rebarreled to .257 caliber, known as the 303-25. One of the unique features is that these cartridges relied less on handloading - and instead factory ammunition was produced by the Super Cartridge Company, Riverbrand, IMI and Sportco.
