I have been requested to provide some information on the propellant composition for 7.62 x 39 cartridges. At this stage all I have been able to determine is that the generic propellant nomenlature is SSNF 50 and that it is a double based ball type propellant. If anyone has any information on the composition of SSNF 50 (ie. stabaliser, NG % other additives etc.) I would appreciate it).
