    Dating UMC 7.62X39 Ammo

    I picked up 260 Rounds of this for $55.00. Is there are way to figure out the manufacture date of UMC 7.62X39 Ammo? The closest I could come to it is from the box design International Ammunition Association put the box as introduced at 1987. The only information I could find on the box was on the inside of the flap stamped;

    G 11 YC3008 and C410B-5 U-3A

    I'm basing this on the coding series we used when I was in the printing industry from the 70's to the 90's it could be right or wrong.

    Month of year is alpha, year is numeric.
    So your G 11 will translate into July 2011. Other letter number combinations will be the actual press operator or manager on duty, shift, job number, customer ID, materials used, time of day as well as internal identification codes. There is also the possibility that the letter I isn't used as to prevent confusion it with number 1. We used I unless instructed not to by the customer. This will id when the box was printed on one of the flaps but not when the ammo was loaded which could be up to a year after the box was created. Any actual ammo information on the box will be a stamping done by the ammo company Identifying the round, loading, lot number ect and will differ from the box printing.

    Thanks for the help, the coding must mean something else because the IAA shows the box design changes in 2004 but you are right knowing the box information would not really reflect the ammo manufacture date.
