Maybe 10 to 12 years ago, I bought several hundred rounds of Russian steel-cased 5.56 FMJ (says L.C.B. 56 grain) ammunition at a gun show, at the amazing price of a dollar per 20 round box. I shot all of it up, but I just ran across one empty box I still have. Box is plain white, but it has all warnings printed on the back side in English, so probably made for the US market.
Box has one top flap only, with one-piece black plastic separator inside of odd design. Front side says: TCW AMMUNITION/.223 REM. (5.56X45 mm)/MADE IN RUSSIA/20 ROUNDS On one end flap is a symbol which is a diamond with three Cyrillic characters inside (which I guess are TCW). The characters inside the diamond look like r - backwards N - c if that helps.
So who or what is TCW? (maybe Tula Cartridge Works?) What does L.C.B. mean? Maybe Lead Core Bullet (like FMJ)? I haven’t seen these boxes anywhere else since.
It was Berdan-primed, so I didn’t save any cases. I should have bought a lot more than I did - it was pretty good-shooting stuff, and grouped well as I remember.
