I don't have the figures on hand, but once when I was dwelling on this matter
with IMO, I looked up the muzzle velocities of .22 caliber bullets and found
out that they aren't traveling fast enough to break the sound barrier. In
fact, only a few high powered bullets in the data I found were fast enough to
break sound barrier. This was a surprise to me.

So are you saying that a .22 caliber bullet is big enough to cause a sonic
boom, but it just doesn't travel fast enough?
