[quote=“AKMS”]EOD, are you saying that all of the Czech. military ammunition with blackened primers since the early 1950’s is non-corrosive primed? The 7.62x39mm short range cartridges “Rd-43” type, headstamped “bxn 81” I tested were definately corrosive primed, and they have a blackened primer. Why would the Czechs be the only Warsaw Pact country to use a different primer type? Interesting that these “almost waterproof” 120 rd packs came to the US with commercial type Hollow Point ammunition with plain brass primers and the first commercial 5.45 ammunition from Russia had blackened primers and were in 25 round boxes. Do the military issue 120 rd. boxes have any markings on them? Any pictures available? I always thought this was just commercial packaging!
This is what the Czechs are saying, I never tried anything to figure if it is or not.
The Czechs had actually quite some own habits when it comes to ammo.
The Russian military issue 120rd carton looks a bit like a milk pack (almost white paper) and the markings are a continous print off a big roll of paper, means the black square containing the caliber and qty. is printed on the box like 5 times to make sure it will appear visible independend from the paper cut.
