What ammunition did China have/use before 125-I, if any? Did they have imported Soviet ammo; as the ZPT-98 cannon is derived from the 2A46M and the Type 88C uses the same rounds? Did China import 3BM15/17, 3BM22 or 3BM26?
I don’t know much about Soviet ammunition export to China, nor Chinese 125mm development, so hopefully someone does.
Also, is the Type 1985-I APFSDS supposed to be 125-I? If it is, why did they change the name?
