Also...I can't see the slug itself on my phone...is it possible that this is a picture of the vapor trail?
Ok, so the exposure is 1/250th of a second... I know this is probably incorrect to assume a constant velocity from the barrel to the end of the visible bullet path...but if you do...
Then: rate x time = distance
Time = .004 seconds
Distance = about 7 times the barrel length of the pistol... How long is that barrell?
We should be able to get an aproximate muzzle velovity if someone can tell us the barrel length.

If my math holds up...the barrel length is probably between 6-8 inches so the velocity is between 875 and 1150 fps.
Keep in mind a wide margin of error in assuming that the length of the bullet trail is about 7 times barrel length.

I've been away from the computer for a day or six. Anyway, I'd bet a dime to a donut that revolver has a 5.5 inch barrel. Looks too long to be a 4.75 and too short to be a 7.5. If memory serves me correctly he's shootin' a .45 Colt. I'd reckon muzzle velocity to be about 600 to 750fps. Birdgun told me the camera was in automatic setting, so there's no way of knowing the shutter speed. Either the shutter closed where the end of the bullet trail is, or the bullet angle took it out of the proper angle for the sun reflection. I'm guessing the later, since you can't actually see a bullet. It's definitely not a vapor trail. I think Birdgun just got extremely lucky.
This.
According to EXIF Reader:
F 3.8
1/250s exposure time
6mm focal length
Canon PowerShot A400
Yep, exif confirms 1/250s. By my math, the distance the bullet traveled is plausible for the aproximate muzzle velocity (875fps plus or minus about 100 fps considering I am estimating distance).
I believe the streak IS the bullet in flight surrounded by a rotating vapor and smoke trail.
Amazing shot that shows no signs (that I can see) of photo manipulation. It looks like the shot does capture the bullet (albeit as a streak) in flight.
...now I'm thinking about how fast a shutter speed id need to "stop" a bullet mid air...and how to time that shot with a dslr limited to 4fps...and fastest shutter speed of 1/8000s....
