Cutaway model of a 76,2 x 385R mm UBR354P HVAP cartridge for M1942 (ZIS-3) field gun. This gun also formed the main armament of the T34/76.

Muzzle velocity: 965 m/s.
Penetration: 92 mm at 500m at 90 degrees.
Weight of projectile :3,1 kg. Length of projectile: 177 mm.
length of complete cartridge: 535mm.

The penetrator exists of a tungsten carbide bullet. Note should be taken of the fact that the core is "glued"in the projectile with mercurychloride (HgCl2) which is quite poisinous. With roomtemperature, the Mercury chloride is a kind of -solidified- plaster of paris that keeps the core in place. Upon impact , the schockwave changes the mercurychloride into a liquid at simultaniously.
When sectioning this shell, gloves and a dustmask should be worn, the workplace vaccumcleaned (no broom) to remove all rests.

regards, DJH

It is unwise to use a vacuum cleaner to clean up toxic powder. Some powder will not be captured by the filter and will become airborne, and spread all over the workshop.

I think you would be better off using moist paper towel to clean up the powder.

Mercuric Chloride is nasty. Exposure to less than a gram can be fatal.
