14,5мм БНС - 14.5x147mm BNS, Russian. Can anyone provide information about this cartridge?

Image of this cartridge was posted by “Sleng1” here:

I assume this is a Soviet/Russian experimental cartridge.

Can anyone provide additional information?



PS: БНС (большой начальной скорости) = BNS (high initial velocity)

yes this cartridge is mentionned in the book " Munitions militaires russes de Philippe Regenstreif

apparently it an experiment for high velocity AP
the belted case is the 23x152B necked down to 14.5

Yes, and be aware of “copies”.

Thanks ammogun & EOD.

Any idea of the time frame for the development/experimentation for this cartridge? WWII?
