Reports on ammunition used by Vietnamese forces before 1975

We all know plenty of various US reports on enemy ordnance coveringy various eras, locations and countries.

Are there any reports known which deal with small arms ammunition the US forces have encountered in SEA/Vietnam?

Any info is welcome.

I have a little 2 volume pocket set of books on captured Viet small arms and ordnance, but I can’t recall if it has much in small arms ammo. I’ll take a look tonight. Perhaps there is an e-link to the books I have.
