I think the problem is that your subject line isn't very clear.

Figure 1. High-speed photography freezes in time an instant of the discharge of a .30-06-caliber rifle. The fast exposure captures the bullet as it emerges at about Mach 2.5, but the spherical shock wave of the muzzle blast and the sweptback shock waves behind the bullet are normally invisible. While this image was captured on film, new digital video technology that can capture the waves' distortion of a background pattern has enabled some classical optical techniques to enter the modern age, where they can image high-resolution details of ballistic events with a large field of view and under realistic conditions. Because flows are standardized to move from left to right in fluid dynamics, some images in this article are printed in reverse.

Sexed up the title

Interesting.

I'd love to see pics of a shockwave affected by bare barrels, compared to the same barrel with various muzzle devices, like the Vortex flash hider.  I thought it disrupts the outgoing blast to reduce muzzle flash.

The last time I got into one of your threads there was a pic of a uber-hairy nekkid guy (In Team)..Can you blame me for being skittish?

now that's cool, once you changed the title, I actually clicked on this thread.

It's safe to go back there, a MOD trashed it after scorching his eyes

They could use a few more photos.
With something that cool, there should be an endless supply of ideas to photograph.
