Another Chinese experimental cartridge.May be 14×110mm

It is says that the 14mm caliber cartridge was developed at the same time with the 20×130mm of the Type 71 anti-aircraft gun.I am still looking for more information about it.(By the way.Thanks @Sheng for the information about this cartridge.)

hello
on your picture the “14mm” case look little slimer than the 14.5x114

Magnum, as per the inner case neck it appears to be a 14.5x114 no?

But as you are speaking of the 20x130:
Do you have more info, images and/or diagrams on that one???
