.50 BMG tip colour code


Can anyone identify for me the nature of a .50 BMG bullet which has a green tip with a black ring immediately underneath? It also has three narrow cannelures immediately below the start of the ogive, as well as a broad cannelure further down.

Thanks for any help.



Is this the one?


Municion has it as a Kynoch experimental AP (ca. 1986).



Yes, that’s the one! Thanks Dave.

I’ve also got that inner core and the jacket separately.
