Would the mic still work even if the bb isn't hitting anything? The mic test I've seen used 1 mic and like a piece of cardboard or something like some distance away. The speed of sound is like..1100fps or something, so the error should be relatively small. You can use two mics, and you'll get rid of the time needed for the sound to get back to the mic, but this can be calculated pretty easily. So it is it 10 ft away, 10/1100=seconds to subtract from the total time between the shot and the impact.
