Might it be a .455 auto blank? Appears to be semi rimmed.


#3

.470 rim
.466
.465 c/m
.922 c/l


#4

Can anyone identify the headstamp?


#5

any ideas on headstamp and cartridge use?


#6

Not me & can’t think what it might be even if I try putting pieces on the letters - F C with a broadarrow? makes no sense. I C I broadarrow, maybe? but not seen that ICI before, still missing an “I” & no hint of one either.


#7

Has a very “Yugo” look to it. Some kind of tool or pyrotechnic cartridge?
