In another thread on the 10mm Mars cartridge, mention is made of a 10mm MAS cartridge replicated by Megret for the French-Speaking Group of ECRA (AFERHM).
I have a cartridge from AFERHM headstamped “AFERHM 2001.” It is brass case and bullet jacket, FMJ RN bullet, brass primer with red primer seal and a very heavy ring around the primer, but not close enough to be a crimp. I have had no luck finding out what cartridge this replicates. It cannot be the 10mm MAS round, even though the case, which is very, very close to the 9mm/360 Mars Cartridge (direct comparison made from my collection), looks like the one on the other thread. However, measured as close to the case mouth as is possible, the bullet diameter is 8,95mm (0.3525") in diameter.
Can anyone, preferably someone “in the know” from AFERHM, tell me exactly what cartridge is supposedly replicated by this round?
I felt that it was a replica of the 9mm Mars, although the dimensions are not perfect by any means. Another European told me it replicates some sort of French experimental assault rifle cartridge. Identification of this round is very important to me. Help wanted!!!
