The .20 VarTarg is a wildcat centerfire rifle cartridge, based on the .221 Remington Fireball case, necked down to fire a bullet. The VarTarg is most popular with varmint hunters because it provides good range (up to 300 meters) and uses relatively little powder, so the rifle barrel doesn't heat up quite as fast. The diminutive VarTarg pushes the projectiles over into the range with much less powder than is used by the .204 Ruger. The VarTarg achieves this performance by using fast, high-energy propellants. The name VarTarg is a portmanteau of varmint and target. There is also a .20 VarTarg Turbo based on the .222 Remington ==See also== *.204 Ruger *.20 Tactical *.221 Fireball *5 mm caliber *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「.20 VarTarg」の詳細全文を読む スポンサード リンク
