Part of the equation to making this work lies in shortening the flash 
duration. I don't know how current strobes work, but I recall that the 
old Honeywell Strobonars could be as fast as 1/50.000 of a second when 
the range was short and the flash was on auto exposure. In fact, I 
think the Honeywell units were used for some of these shots.

Tom,

Those were photos from Doc Edgerton's lab at MIT.
They used some good size flash tubes, and
I believe a microphone was used to trigger the flash.
Polaroid film and open the shutter, fire the gun,
which triggers the flash, and you see where the bullet is.
Then, adjust the microphone closer or farther away from the gun,
to get the bullet where you want it in the frame.
I have his book somewhere.  The photos are amazing.

I've been thinking about trying some low tech "bullet through apple"
photography. I'm still puzzling through a trigger mechanism to trip the
shutter and get the flash to fire. Has anyone tried those light beam
triggers? How wide is the trip beam? Would a bullet break the beam 
enough to
trip the shutter? Does anyone have any ideas for a lower cost trigger?
