EOD - thanks for the clarification. Actually, I knew that there was some interest in the round by the Soviet military, or at any rate, an attempt to interest them in it, but the story around here when the first FMJ “T” headstamp rounds showed up was, basically, that it WAS the new Soviet military round - very secret and very rarely found. The usual hype similar to the stories about the “Special, secret KGB 5.45 x 18 mm pistol round” that went with each specimen sold to collectors, when it fact, the round was covered quite openly in one of Zhuk’s books, in Russian, sold in any Russian book store to anyone who wanted to buy it. I have the book now in my own library, although of course, I can’t read hardly any of it.
Of course, there was nothing special or secret to the 5.45 pistol round, and it was not at all limited to KGB use.
