Example in the book:  drop a bullet at the same instant that you shoot a bullet with the barrel parallel to the ground, and the bullets will hit the ground at the same time.


I had trouble with this:  it would seem that if you used more gunpowder in the bullet it would go farther, but the time it takes for a bullet to drop remains the same.

It really does work that way.  You can demonstrate it if you have access to a still lake when no one is around.  Get a sturdy table or something on which you can clamp your rifle, get a precision level, or even a good old carpenter’s level will do, mount it horizontally, fire.  Note how quickly you see the first skip out there, a fraction of a second after you pull the trigger.

 

If you decide to do that, note that the slug will skip a bunch of times so make sure it is a really big lake.  Otherwise, see if you can find a YouTube where a different yahoo came up with the same idea.

 

Here’s MythBuster’s pretty good version of it, but Carrie Byron isn’t in it:
