The slam fire maybe avoided by using CCI military type primers. No. 34/7.62MM
Military large rifle primer with NATO sensitivity.
The line on the brass is start of a separation from to much Head Clearance or to many loadings. Some gas guns stretch the brass on opening early. The fired brass maybe longer, head to datum, then the chamber. From what i read. I dont own one. Good reading, the Service Rifles. http://www.exteriorballistics.com/re...sgunreload.cfm
