Ammo just happened to be what I caught on video but I will be posting others with CCI and some gemtech subs. For audio I have a B&K pulse system. Thing is no joke. The larson davis setup is interesting but I don't believe it will get you accurate results since its got a 51,200Hz sample rate which isn't really fast enough to catch the rise and the pulse system I use is 102.4kHz per MIL-STD-1474D.
