I assume the spiral pattern comes from tracer rounds that tumble.
1st:sorry for my bad english

2nd: The shell comes from the barrell rolling on his own axis.all modern guns (ww1-ww2 included) have this type of barrell.



3rd: the rolling smoke tracer is the consecuence of the fast cooling of the shell (high altitude) plus the "2nd point"
