You've got a severe case of ammo.
Your problem seems to be thats its bottled up inside these sardine cans.
As a medical professional I recommend an intensive course of fire followed by further checkups.
Looks like corrugated cardboard to me.
Yeah, that's definately cardboard. Move those two tins of Russian 7.62x39 ball fmj out of the way so we can see it better.
I realize that it's a reference to the TYPE of powder. I want to know WHAT type. I already know its steel core ball fmj steel case
What do you intend to do with that information ?
Well I was just hoping someone could "translate" the type of powder. I've got the rest, but my google-foo is failing me on that part. I don't really care, it's going down the barrel either way, just kinda interested in what all the markings mean. In English.
Here's what I found:
вуфл:
pyroxylin powder brand VUfl. Pyroxylin powder, smokeless. The letter "V" is-a rifle, the letter "U" - reduced (reduced geometrical grain size - less than pyroxylin powder VT) the letters "PL" - powder phlegmatized (added deterrent to reduce the burning rate). Used in 7.62 mm cartridge model 1943
"133/78 K":
133 stands for gunpowder batch number, 78 - year of production, K - factory code.
"ПСгс":
steel core bullet with steel case
Sorry couldn't find what "Л-74-79-711" means - it's probably some factory code.
