Quote: the belt is indeed useless you need it only in big machine canons. you will find that any machine canon over 30 mm caliber use a beltet or rimmed case. why, when the rimless case with an extractor groove is the very best design for an automatic action? such machine canons handle the rounds with such brutal force that cases making headspace over the neck will be set back when chambered. only belted or rimmed cases will be strong enough to handle such power and hold the original head space. |
