I'd still like to know what specific ball powder was so bad.
wrt jamming, the type of powder (stick vs ball) is way way down on the list of things that can cause an M16 to jam.
There’s some good source content linked in the article below on the problems with the early M-16/XM16. There’s a section on powder implications.

How bad was the M16 during the Vietnam War? And can you trust it (and the civilian AR-15 variants) today? We cover it all.
