This full-scale schlieren image shows the discharge of a .44 Magnum revolver. Two spherical shock waves are seen, one centered about the gun’s muzzle (the muzzle blast) and a second centered on the cylinder. The supersonic bullet is visible at the far left. This weapon produces a bright muzzle flash and a cloud of products of gunpowder combustion that envelops the hands of the shooter. Such high-speed images help forensics experts understand the transfer of gunpowder traces to the hands when firing a gun.

You took this?? Is that a piece of reflective cloth behind or a HUGE field lens?

Full size Schlieren images are hard enough, let alone high speed ones. This involved some serious equipment!

Hat off to you, that's gotta be a hell of a shot to set up. Can you imagine doing it on anything other than digital?

This image was taken by Gary Settles at Penn State University Gas Dynamics lab and I believe is copyrighted to him. I suggest you remove it.

Not surprisingly, the biggest shockwave comes from the millimetric open space between barrel and cannon. That's the reason almost no revolver can practically use a gun silencer (opposite to the semi-automatic pistols) - you simply can't damp the barrel shockwave. The only revolver physically capable of using a practical silencer is the Nagant M1895, in which the hammer, when cocked, pushes the barrel forward after rotating it, effectively sealing the gap between barrel and cannon, thus eliminating the gas escape through it - and eliminating this sound source, leaving only the cannon muzzle's one to be dealt with the silencer. Also it adds this otherwise lost gas pressure power to the bullet in the cannon, increasing the muzzle velocity and hence the firepower.
