    I've seen those before. The multiple gas expansions from the muzzle are interesting.
    There is out there somewhere a baseball grenade exploding in slow motion. It balloons out before bursting.

    So the secondary "bubbles" are the result of the water slamming back into the void created by the gas. In the secondary bubbles its the water rebounding from hitting itself and compressing the residual gas and it repeats until the gas is able to totally escape the area of the initial bubble.

    The way a depth charge destroys a Sub is by creating a huge void in the water. As the water rushes back in to fill the void it creates a huge shock wave as the water hits itself. Same thing here.

    So the bubbly section closest to the muzzle is the bullet and muzzle blast, then the second large bubble is the just the bullet.....o_O?
    So, smart guys, why does it separate into 2 sections ?
    Is it the muzzle blast shuts of fast enough to cut them in two?

    Of the two big bubbles, the first one is the shockwave from the bullet and the second one is the expanding gasses.
