The spiral effect of the smoke was not a camera shake issue. The spiral like vortices were actually present.
I had a 20mm MG-FF cannon shell pulled from a shot up B17. The hole for the tracer was off center. This is another contributing factor to the spirals.
The only thing about the wiggling tracers that I have an argument about is quite simple.
When viewing a tracer that is fired, it will appear as a streak traveling in a straight line, no wiggles, BUT if you are firing a handheld or semi fixed machine gun, the vibrations and recoil on your face will cause the tracer to appear a little distorted, very much like the camera shake.
