Polish 10x99


Any information on this Polish 10x99 anti tank round? What weapon fired this cartridge? Anybody read Polish? I can not read what is written underneath and do not have a better sized picture.


I may be able to help you but I believe even a native speaker cannot decipher the text under this photo.


click on the picture and it enlarges it just a bit. I would assume the English caption below, much of which can be read, is a translation of the Polish.


The resolution is too poor to read anything, but I do see the word experimental in there somewhere


This polish experimental anti-tank cartridge was designed in 1939. It’s based on the 13,2 x 99 mm Hotchkiss Mle 30 case (no headstamp). The real bullet diameter is 10,35 mm.
