I recently heard an anecdote about someone getting shot at in a heavy fog. The person claimed that "when a warm projectile is sent out through the fog, it leaves a tracer round effect. Meaning if you are quick, you will be able to see the trail of where the bullet came from".
Can some of the gun experts here tell me if that's nonsense? I've never seen an effect like that, but have never shot in the fog.
Thanks.

I believe you'll be much too preoccupied with seeking cover, to be able at all see much of anything travelling at modern centerfire bullet speeds. /ubbthreads/images/graemlins/wink.gif
But, supposing you could "rig" up at observer-protected study of such a phenomenon, I believe there are simply too many variables to give you a concrete answer. Much would depend on the fog density, lighting factors--both direct and indirect, and distance from the shot's origin (which has an effect on the speed at which the slug is travelling).
Additionally, a big variable would be the type of firearm fired. Observability, I'm sure, woudl vary a great deal between say a relatively "slow" moving .45ACP slug moving at roughly 900 fps vs. a "speedy" 5.56x45mm (.223 Rem) bullet moving at 3200 fps.
That's my guess.
