centrefire rifle cartridge, based on the.303 British , necked down to fire a .257 projectile, originating inAustralia in the 1940s as a cartridge forsporterised rifles, particularly on theLee Enfield action, similar versions also appeared inCanada around the same time [Barnes, Frank C., Cartridges of the World, 7th Edition, p173] .The .303/25 was very popular for a number of reasons, one being that the .25 caliber was better suited to small game than the .303, the rifles were cheap and plentiful and in
New South Wales ownership of military cartridges was severely restricted. Several versions existed but most were simply necked down and remained full length. Although Lee Enfields were the most common, conversion of other rifles mostly suited to rimmed cartridges such as P14 Enfield,Martini Enfield , 1885 and 1895 Winchesters were often seen, as well as 98 and 96 Mausers [Barnes, Frank C., Cartridges of the World, 10th Edition, p473] .Loaded ammunition and brass was produced by the Super Cartridge Company, Riverbrand, ICI and
Sportco , some using new Boxer primed cases, others using military Berdan primed cases. Cases can be formed simply by necking down .303 British brass available from Remington, Federal, Winchester, Sellier & Bellot and others. Reloading dies are made by most larger manufacturers, like RCBS, Lyman, CH [ [http://www.ch4d.com/ CH] ] and Simplex [ [http://www.jansa.com.au/simplex3.php Jansa Arms Co - Australia ] ] .ee also
