I'd think detecting gunshots using a mote would depend on how good a shot you are unless it's really close range...
But you probably want to do audio sampling, right? I'm afraid I pontificate on that subject because I know about it in general, rather than having done it with motes, so I can't help more than to recommend that you look at the High Frequency Sampling app example. The standard Timer component has a low end of 1-3ms depending on your TOS version so it's of no use for this. I think there are faster timers available, like the JiffyTimer, or you can experiment with free-running the ADC using an appropriate clock pre-scale value. I suspect there are sample timing jitter problems with all the possible techniques so you probably won't get good audio but should be able to get enough to detect a short-sharp-sound.
