Great folks here have posted lots of info on the 35mm round for the Chinese QLZ-87 grenade launcher.
Sectioned examples of the DFJ-87 show that case to be a High-Low pressure type (I assume).
What about the DFP131?
Externally it looks just like the DFJ-87 but no internal “high pressure” chamber, just a big ole empty case.
Is this a round for the vehicle borne ZLZ-94?
Thanks for any info.
