I found a 7.63 mauser ctge
brass case, tombac bullet, 6 dots crimps ( big ones and 3 small ones)
the hdstp is A (9 oc) T.C (12 oc) F (3 oc) A (6 oc)
Could you confirm it is turkish ?
It seems to be a dummy because
- The primer looks to be fired (there is a dot on it)
- on one side of the neck there is a split (you see it just on the right)
I think it was a regular ctge (with the 3 small crimping dots), then unloaded and primer stuck, and reloaded (with 3 big crimping dots)
What do you think ?
