I confess, I know nothing about small caliber ammunition and have no clue what kind of bullet this is. What I found interesting was the way the projectile is attached/crimped into the case. It looks as if it has 3 very tiny pin sized dents at equal distances from each other. I have never seen or noticed this before in any other ammunition I have come across. Is this normal and what kind of bullet is it. Is this a Makerov (My only guess).
PS: My Godson found it with a few other rounds at South Beach in the sand.
