Hi,
It's possible to get bullets that travel at subsonic velocity. They
make less noise. Even supersonic ones are not that fast, I think.
700 mph is quite fast! The reason I thought about it was that one of
my friends has discovered rats in her garden. I toyed with the idea of
getting a

Polaroid film and open the shutter, fire the gun,
which triggers the flash, and you see where the bullet is.
Probably an air rifle pellet would still be in the barrel if you used a this

I'd have thought a fairly simple switch activated mechanically by the
movement of the trigger would be a lot easier.

bullet velocities can vary between 700 fps and 2300 fps for common guns.
There are other
For 22 cal. rifle and air rifle there are small commercial bullet traps available
at low cost, less than $50. They do an excellent job containing the bullets.
A switch on the trigger worked for me.

Hi,
But wouldn't large(ish) calibre bullets make a mess of what you're trying
to photograph - depending on subject, of course? If it was an egg, for
instance, wouldn't an air gun pellet make a more interesting shot than a
.22 round?
there are some interesting examples here of someone

I would have thought a light or electric trigger would be better.

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

Actually, Bob, many bullets are sub-sonic ...
2x faster is possible, AFAIK, but I can't recall
reading of any at 3x the speed of sound.
Perhaps some high powered rifles will get
up close to that speed.
