Some of the early general radio corp strobes had speeds down to 1/100,000th second or so, IIRC, but at very low power settings (a few watts on that early unit). I suspect that most thyristor controlled cheapy amateur strobes probably get down to about 20-50 microseconds, depending on design and sensor illumination. as noted a lot of films do poorly at sub millisecond exposure times ;-) True, I went through this years ago and it seemed like a never ending puzzle, low light at frightning fast speeds caused underexposed films due the already mentioned reciprocity effect, large amount of light meant "slow" flash durations, I did not use the laser trigger mentioned before, but a sound trigger which worked very well I might add, adjusting the sound trigger meant moving the sound pickup, The sound trigger which was adjustable and very cheap and easy to construct, did not need sight to function,  as in trying to break the beam, you may give it some consideration. Some other ideas, low power charge for the bullet, high speed film, I can't remember if two flash tubes with one blinded at low power setting helped or not. What ever you do find that does work please keep us posted. Chris of Bradenton Fla.
