Found this thread searching for something else, but thought I should write some lines about this cartridge since I know more about it (although the thread is old).
This cartridge is Swedish and is the new standard 5.56mm round for the Swedish army. It is environment friendly ammunition, in this projectile the led core is replaced with steel. The primer is also changed so it is more environmental friendly. The only visible difference between the old Swedish 5.56 round and this is in the two lines 10 and 2 a clock in the head stamp.
In Norway we use the same round, but with a different headstamp. Our headstamp is with the NATO cross and LOT-CG-YEAR (E.g. 06 - CG - 08). Norway has recently introduced the 5.56mm cartridge as a standard round together with the introduction of the H&K 416 rifle. The ammo used in both the Norwegian and the Swedish army is produced at the NAMO factory (NAMMO Vanäsverken, Karlsborg, Sweden) and in the beginning we used some cartridges with Swedish headstamp.
The same factory has had several names during the years and ammunition from this factory can have headstamp like CG (the old Carl Gustaf name), FFV (the old FFV Vanäsverken name) and 070 (this is used on many Swedish military cartridges)
So, the conclusion is that this cartridge is most likely bought from Sweden.
