You must'a ducked!!

And just for the record, that bullet demonstrates a most exaggerated example of yaw as it was a .30 cal tracer run single-shot thru a 7.62x25 TT33 Tokarev pistol. I keep a few of those as signalling rounds for survival purposes for my ski jaunts. Kinda like road flares.

Same bullet shot from a .30-06 at normal speed shows a less dramatic helix. Still visible, but less dramatic. For really eerie pyrotechnics, launching tracers into the night sky during a fine snowstormor into light clouds takes the cake!
