7.62mm(308")一個公制,一個英制......ms高5尺八......約1.7m.....明未

actually the bullet diameter is 7.8mm (.308 in)
i don't know why it's called 7.62x51...

beside, the military rounds(7.62x51) usually have higher pressure than civilian rounds(.308)

308民間叫法,7.62係軍隊叫法........常見有
7.62x51
7.62x39
7.62x54R
ms在cgf送唔少喇

問題係,點解彈頭直徑明明係7.8mm(.308),7.92mm(7.62x39,7.62x54)
都會叫7.62?
