Depends on the sophistication of the system, and how many microphones it has. The vast majority, if not pretty much all of this class of gunshots, are going to start with the bullet being supersonic, the shock wave of which contributes to the signature (in the case of sniper fire I mentioned elsewhere in this discussion, it will tend to fool people into thinking the source is as much as 90 degrees from where the rifle actually is).
I'm having difficultly coming up with anything that isn't essentially a blank firing gun, and I'll note those are deadly really close up.
