Hallo,
hier mal 2 von der Länge unterschiedliche 2-cm Hartkern-Geschosse (aus dem Ofen).
Im letzten Bild kann man die Teerspat-Vergussmasse noch erkennen.

Dscheto, die "Teerspatvergussmasse" sind Reste des Brandsatzes die den Kern mal umgaben. Ferner sind dies keine Hartkerne im eigentlichen sinne (WH-Sprachgebrauch) sondern lediglich gehärtete Stahlkerne.
Die Geschosse sind russische 20x99R SchVAK. (engl. ShVAK)

Danke für die Aufklärung, so kann's einem gehen, wenn man was mitnimmt, ohne selbst damit zu arbeiten.
Die Suchfunktion brachte die engl. Bezeichnung API und Thermit als Füllmasse. Durchschlagleistung 24 mm Stahl auf 100 m. Dank an Pzgr.40's Beitrag von 2004!

It had the same tungsten core as the 45 mm AT gun AP shell.

"Normal" steel core because of the War is ended for the Hungarian industry in December 1944.

More versions:
- Aluminium head, but without steel undercore-cylinder
- Steel sheetmetal windshield and core with steel cylinder

At the moment I am busy with a cutaway model of a steel cored 40 mm Hungarian projectile depicted above. Does anybody know the exact shape -in and outside- of the aluminiun or zinc nose? I suppose the outside resembles the normal 4 cm HE or practice HE projectile. But what about the inside? Is at a hollow cap or does the inside follow the shape of the penetrator -so a "solid" cap-.
Thanks in advance, regards , DJH

If my memory serves, it is a hollow cap filled with incendiary

[PzGr40]

Hi Vince, thanks. I made some drawings of the projectiles. Lowest in the row are the HE-T silhouette and cutaway (01 & 02). Above that a drawing of the APHC body after removing the core (03).
As the shape of the body’s outline is the same with both projectiles I suppose it will be the same for the shape of the nose (04). With drawing 05 I inserted the core. It occurred to me –while removing the thread remains of the APHC that the thread of the cap ended 8 mm below the top of the thread (line A) of the projectile body – the full thread is 12 mm long-. The thread of the HE-T is the same, in fact one can screw the cap of the HE on the APHC body.
So in drawing 06 I tried to reconstruct the most likely inner shape of this cap. In 06L I made the part (thicker line) parallel to the thread straight, and than made it follow the arc shape of the outside. In 06 R I started to make the inside of the cap follow the full arc from top to bottom.
The 06L looks more plausible to me, however I would be more than interested to hear your opinion about this.
Thanks in advance, regards DJH

The projectile in 3D as I think the nosecap must have looked, the outlines of the projectile same as the HE
