Yugoslavian Panzerfaust - The M57 Infantry Antitank Weapon

[Stray]

Just wondering if anyone knows the weight of the propellant charge used in the 57? Is it smokless or Blackpowder?
Thanks.

The whole propellant charge weigts 0,65 kg, but about half of its volume is filled with sand (countermass). The smokeless powder is NC25.

OK. I've just found answer in previous page photo: 96 g!

The propellant charge contains 24 grams of black powder,100 grams of the monotubular graphite powder (Simple base) and a sand countermass.

So the Graphite is simply there to add volume to the black powder, Or does it serve another purpose such as protection against static electricity and making it more stable?

No, the Graphite is just a tiny coat on the simple base powder. The powder itself is made of nitrocellulose. But the graphite is indeed against static electricity. Many propellants tend to generate static electricity during drying. Thats why the graphite coat is for.

Ah I misread it, thought that he was referring to graphite powder as a simple base rather than a graphite coated nc based powder. Makes much more sense now, thanks.

How iss the powder arranged in the cartridge? From the "cutaway" picture they have it looks like a tube of powder surrounded by a different powder. Is it a tube of bp surrounded with nc powder, or am I completely off? Really haven't been able to find much real info on it.
