some 0.38 revolver identifaction

[Davidavid]

hey everybody,

i got this 3 rounds from friend, and he told me that was from his father's old colt gun (revolver of course).
as you can see they are not FMJ, they have no metal jacket at all - just lead.
the shell itself is just a little bit higher that the normal 9x19 shell, and the slug (ptojectile) is little longer that regular 9mm slug size.
it have some crimp that fixing the slug at it's place (so it wont move) like the old ammo style. the nose is pretty flat. the rim says: "REM-UMC 38 COLT NP".
i added a pic of the cartridges and of the rim so you can help me ID this.



thank you all,
david.
