Is sonic crack at all dependent on velocity above the sound barrier? What I mean is for example. will the same 55 gr 5.56 bullet make a louder sonic crack at 3100fps than it will at 1100, or is a sonic crack a sonic crack period. |
The short answer is yes, the shockwave produced at higher velocities is a stronger shockwave. Is it louder? I guess you can answer that by comparing the crack of a .22 against that of a .223; even though the bullets are different shapes, which does affect the shockwave, the drastic difference in velocity should provide you with an answer regardless. |
Suppressed supersonic .22LR doesn't sound much different to me than .223. I'm sure there is a little difference, but probably not enough to notice. |
