Saw a shorter video on Facebook with Johnny Cash's "Ring of Fire" playing, but couldn't find it on You Tube.
I always thought it was a result of the vapor trail from faster bullets, vapor trail forces the flame around the path of the bullet forming the ring. Would be interesting to find out exactly what causes it.I'd love to see it with super high speed film to understand how it is formed. I bet it is not coming around the bullet - but what in the heck creates the ring?!
Seen plenty of fireballs. That's a new one on me!!!
IF thats anything like "MAGIC" then I agree, that was my guess anyway!I would postulate that the bullet creates a temporary vacuum in it's wake that is filled with the already expanded gases that created its propulsion so the remainder of the flammable gases and unburned powder ignites when it reaches the air in the atmosphere out side of that "trailing" effect.
