The muzzle blast is rather quiet relative to the crack of the bullet when the bullet is closer to you than the rifle is. The witnesses probably heard that and probably assumed that they heard the actual discharge.

Again, the likely scenario is that the witnesses are hearing the rifle blast........

No, it isn't, unless the shooter is right next to them.

Look, I've probably fired more rounds, and have heard more rounds going past me, than you have.
