Any truth to this?

I've heard of it before and it makes sense, scientifically speaking, but I'd never seen it. Very cool video.

30 seconds in.

That is very cool, thanks.

I would imagine that it'd actually just be the distortion of the air (vs boiling water) caused by the bullet travelling faster than the speed of sound, similar to the visible "wave" of a sonic boom.

They made a point on this on the History Channel's sniper episode dealing with the confirmed over 1 mile kill in Afghanistan

It's the same phenomena happening in this photo


It's a pressure wave vaporizing the moisture (boiling) not heat.

The trail is very clear in that video, awesome. Thanks!

Air flows exactly like water, less resistance but the same. If an object can leave a trail through the water it will do the same in the air. I'm not 100% on the boiling part of that but it's displacing the air and that forms eddys behind the path of the bullet.

Thats exactly what I was thinking.
