I was going through some of the stuff I have for the meetings and noticed that some of my boxes of 7.62x39 and 5.45x39 were marked "Made in Russia" instead of "Made in Ukraine". The Russian rounds are marked "UL" (see below) rather than the "LU" of the Ukrainian made rounds.
Note that the factory code on these rounds is different from the code orientation on the Ukrainian rounds.
I think I have taken 7 or 8 of each of these to Europe during this past year without noticing they were Russian. If you got Red Army in these two calibers from me, check them and make sure what you have.
Always something new. One of my best sources of new items for my collection seems to be looking through my "dupes".
