I don’t see it. All I see is smoke and some sparks. Sorry if I’m being daft.

Not shown: shockwave

Nice picture but not a shock wave. Notice where the distortion is. Because it's coming from the chamber area, I doubt there would be enough energy to produce a visible shock wave, let alone from a starter gun round with reduced grain count. A shock wave will almost always come from the end of the barrel. We are seeing heat waves. Still cool though!
