7,92 mauser inside destrution


#1

[quote=“laurent”]Hello,
I know this subject had already been discussed before, but I have a couple of these steel cases and it seems that this problem doen’t occure with all kind of loading.All seems to be in good condition (still can hear the powder moving into) except the 2 in red wich are destroyed by rust.

I have from :
-eej (Märkisches Walzwerk GmbH, Straussberg bezirk Potsdam):
7 grenade launcher cartridges,1 SmkL’spur-Zdh43,1 sS.
-dnf (Rheinisch-Westfälische Sprengstoff A.G., fábrica de Nürnberg-Stadeln):
2 grenade launcher cartridges.
-cg (Finower Industrie GmbH, Finow/Mark, Brandenburg):
1 beschuss,1 nahpatrone,[color=#FF0000]1 sS anschuss[/color].
-aux (Polte Armaturen und Maschinenfabrik A.G., fábrica de Magdeburg):
1 Sme-Zdh43,[color=#FF0000]1 Smk-lang[/color].
-edq (Deutsche Waffen-u. Munitionsfabriken A.G., Wesloerstraße):
1 sS-Zdh43.
-dou (Waffenwerke Brünn A.G., fábrica de Povaszka Bystrica):
1 Sme.
-hrn (Presswerke GmbH, fábrica de Metgethen):
1 Ls.[/quote]

Finower and Polte used to produce special loadings, what let me believe that they are high-quality working before I discovered these two cartridges with this kind of problem.
So my question for the specialist of this kind of cartridges is: Do you believe that we must pull out all these cartridges? I know some Beobatchung loaded on iron cases, how to do it without an inertia bullet-puller?

You have two choices, since it is the powder that corrodes the case:

1- you pull the bullet and dump the powder, but the original crimp would be destroyed by the operation

2-you drill the case and extract the powder

I would put some oil or other stuff inside the case to stop corrosion.

Anyway, I have recently pulled a bullet from a steel cased 7,92 cartridge that slept under the ground for over 70 years. The outside case/bullet surface was heavily rusted, but the inside of the case was nearly perfect

hello
nevers drill a live round especially a steel case
it’s the best way to lost fingers ,eyes or life

Yes Pivi, it is not a general problem.

Some powder lots have to much acid left. This destroys the case from the inside.
It is also impossible to give you a lot number of a good and a bad powder load.
You can Identify the powderlot only on the box label.

I have from :
-eej (Märkisches Walzwerk GmbH, Straussberg bezirk Potsdam):
7 grenade launcher cartridges,1 SmkL’spur-Zdh43,1 sS.
-dnf (Rheinisch-Westfälische Sprengstoff A.G., fábrica de Nürnberg-Stadeln):
2 grenade launcher cartridges.

The grenade launcher cartridges have other powder. (NZ. T. P. (1,4.2.0,5/0,25) So I don’t think you have any problems with them.

-cg (Finower Industrie GmbH, Finow/Mark, Brandenburg):
1 beschuss,1 nahpatrone,1 sS anschuss.

Also the „Beschuß“ powder is different. “Nz. G. Bl. Besch. P. (2.2.045)”
The sS Anschuß is a different story. They used normal powder.

-aux (Polte Armaturen und Maschinenfabrik A.G., fábrica de Magdeburg):
1 Sme-Zdh43,1 Smk-lang.

The SmE Lang did not have a primer 43. Only a primer 30/40

-edq (Deutsche Waffen-u. Munitionsfabriken A.G., Wesloerstraße):
1 sS-Zdh43.

“edq” never made sS rounds with a primer 43.

[i]-dou (Waffenwerke Brünn A.G., fábrica de Povaszka Bystrica):
1 Sme.

-hrn (Presswerke GmbH, fábrica de Metgethen):
1 Ls.[/i]

Cases could be loaded in other factories.

Thank you for answers, so I hope than I will not lost enought cartridges.
Dutch excuse me, I had a look to my cartridges and what I called Zdh43, was in fact Zdh30/40 with the a full painted primer. So only cartridges like sS or Sme could have this corrosive problems?

Give also attention to the SmK Lsp.
