I attached four photos of some of the ADEN/DEFA rounds in my collection. Three of these I have no information on and would like to see if anyone else does. The first is the right hand round in photo no. 1. It is South African. The exposed projectile is 8 3/8" long. The forward part is non-magnetic and has a rough dull gray finish. Below that is a thin plain steel band, then an aluminum section. The rotating band is iron. The headstamp is: 30mm R1M2 A 79 SE. Someone has written "Experimental (ND not HE)" on the case. The overall length is 9 3/4".
The second unknown is the 2nd round from the right (Projectile separated from case) in picture 4. When I got this round I was told it was an experimental high velocity loading. The case is 5 1/16" longand unmarked, No primer, but the pocket is large, about 1/2" diameter. No markings on the case. The projectile has no markings and is 3 1/2" long with an aluminum nose plug.
I was told that the last one, the right hand empty case in picture 4, was an experimental ADEN/DEFA case. It is a steel and plastic case with no primer. Personally I think it is an experimental case for the U.S. M700 series 30mm rounds for the Apache helicopter chain gun, but I can find no information on it in either case.
