Czech ZVV 7.92x145 anti-tank rifle round


#1

The photo below of the Czech ZB ZK-382 of 1938 was posted in THIS thread:

It was adapted by Germany to make the MSS.41 in their usual 7.92x94 calibre - but the ammo in this pic looks quite different (does it have a two-part case?). Anyone have any details?

I once read that the Czech original was chambered in 15x104 MG calibre, but it seems not!

Before WW II Zbrojovka Brno make experiment with a number of types anti-tank rifles in a few calibers (15mm, 12mm and 7,92 mm). Along WW II were manufacture rifles for cartridge personal construction 15x104 (15 mm Besa). These cartridges have had indeed small effectivity.

Head is able to have two longitude - 22 mm (photo) and 8,6 mm. Sort on weight powder meanwhile isn’t know. Bullet has been probably armour-piercing, weight now also isn’t know. From archives Zbrojovka Brno succeed find out data for speed - muzzle velocity is 1.270 - 1.320 m/s. This is very very high gear and penetration have to be very good. These cartridges wasn’t normal manufacture.

“This is the Brno 7.92 ZVV from 1938, case length 145mm. Besides all-brass case, there were versions with (at least) 2 lengths of steel head, 8.65mm and 22.1mm (shown in the photo), which was quite probably the “standard” one.” From Woodin lab
