The 6mm AR is a centerfire wildcat cartridge designed by Robert Whitley〔http://www.6mmbr.com/gunweek068.html〕 for long-range performance in an AR-15 rifle. The cartridge uses a 6.5 Grendel case that has been necked-down to accept a 6 mm (.243 in.) bullet. The 6mm AR takes advantage of the wide variety of .243 in caliber bullets. Slim, long bullets with high ballistic coefficient are ideal for energy retention at long ranges.〔http://6mmar.com/6mm_AR_Loading_Info.html〕 ==See also== *List of rifle cartridges *Glossary of firearms terminology *.223 Remington 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「6mm AR」の詳細全文を読む スポンサード リンク
