In the recent thread about the “purple” .40 S&W cartridges it was mentioned that Olin (WCC) 9x19mm head stamps from after 2006 or so were generally unknown. If it is of interest to anyone, I have the following:
(nato) WCC 10, 11, 12 and 13
(nato) WMA 13 and 14
9MM LUGER WIN 13
W C C 0 9 and W C C 1 0
also, WCC+P 04 (included just because I’d not seen +P in a “military” head stamp before)
There might be more in my coffee cans full of empty brass, but they seemed so common to me that I never thought to set any aside.
