Hey all, I recently got a load of casings from another collector and while most of them are identifiable by the caliber on the headstamp or matching with identical ones, 4 of them have stumped me. Even with searches I haven’t found an answer. Photos provided have reference cases, .223 remington to the left and .308 winchester to the right.
Cartridge 1: Headstamped FC (top) 04 (bottom)
Cartridge 2: Headstamped 06 (top) 19 (bottom)
Cartridge 3: Headstamped PS (top) 75 (bottom)
Cartridge 4: Headstamped MF (top) 7(left bottom) 55(right bottom) I’m pretty sure this one is a .303 but I’m interested if the 55 dates it to 1955
Many thanks if you guys can identify these!
