For some reason, I saw the name of the posting and I knew what it
was about...

The lines you saw are similar to the "streaks" left by aircraft in
the sky.  I notice the same thing with my .22-250 on muggy summer
days.  The trail comes from the high pressure at the front of the
bullet followed by the lower pressure behind the bullet.  This 
creates a very long "cloud".  Want proof ?  Try taking a coke
bottle, and putting a small amount of water in the bottom.  Take a
lit match and drop it into the bottle.  Now blow as hard as you can
into the mouth of the bottle, and then release it quickly.  The
bottle should be filled with a "cloud".  Neat, eh ?

Adults should get the permission of their kids.
