It was discussed that the adage may come from fish packed into a barrel for transport so the idea was that you were going to hit a fish so long as you hit a barrel... Or you bring an M134.
If I recall correctly, the MythBusters episode showed that the shockwave from the bullet in water could take out most of the fish in the barrel without even hitting them.
