      Those circles are micro cavitation waves. where the air is being compressed to what I would call the "bounce back point where it meets the next compression /cavitation circle and they just cascade behind it. a lot like a large ship seemingly drains the water behind it then it fills back in. but this is moving so fast that it sick air from the air that's already been compressed.

      @Sewan & Sawen Creations Well, any amount of exposure to loud sounds in the decibel range of a gunshot will likely cause permanent damage to the function of the ears if encountered often and without adequate hearing protection. The same can be said of people working in heavy machinery, industrial factories, construction, freight, airports, and aviation just to name a few.

      I would have loved to see a .45 fired as it travels much slower and I wonder if the waves would have started more towards the ends and not the middle, then out of a suppressor.

                It is interesting that the gun does not recoil until the bullet is well clear of the barrel.

                    " SUBSONIC".....ppffffvvvtt!...Cracks me up how guys thing subsonic is " higher performance". It is SLOWER. The FBI developed sub9 mils for suppressor
                    stuff. Quieter, not " faster".

                        Smart people are dying for someone to ask them a question, so they can explode. I think if they don't let that out, they'll die. Cool video man.

                            They make these bottom barreled revolvers. It puts that shock wave right next to your fingers.

                              How many of you , can not only appreciate the beauty of shock waves , but also the turbulence in the wake of the bullet and in the expanding blast ?

                                I would love to see a video about transitional/intermediate ballistics with different muzzle devises like flash/sound suppressors, compensators, etc... like how the waves change, reduce the sound and direction of the waves. Or even how those waves or gasses not coming out symmetric chance the bullets path and accuracy.
