The .222 Rimmed is a centrefire rifle cartridge, originating in Australia in the 1960s as a cartridge for single shot rifles, particularly the Martini Cadet action.〔(Reload Bench )〕 Performance is similar to the .222 Remington on which it is based however loads should be reduced as the walls of the brass cases are generally thicker.〔Barnes, Frank C., Cartridges of the World, 7th Edition, p158〕 Extraction of cases that have been loaded to higher pressures can be difficult due to the inefficient extraction method utilised by the Martini Cadet. Cases and loaded rounds were originally produced by the Super Cartridge Company.〔Barnes, Frank C., Cartridges of the World, 10th Edition, p473〕 Brass is now available from the Bertram Bullet Company〔(Grafs )〕 or can be made from 5.6x50mmR RWS cases.〔 The .222 Rimmed has also been used as a parent case for wildcats, similar to ones based on the .222 Remington, such as rimmed versions of the .17 Mach IV, the .17-222, and the .20 VarTarg.〔(Saubier )〕 ==See also== *.222 Remington *Martini Cadet *List of rifle cartridges 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「.222 Rimmed」の詳細全文を読む スポンサード リンク
