Many years ago I saw a concept of a guided machine gun bullet in a "scientific" magazine; the concept involved steering by a mechanism that moved a lump of mass within the bullet around.

How in the world does that work? Bullets spin at ridiculous rates; some 3000 RPS. At long distances it'll have made over 10k revolutions before it hits the target!

I honestly don't know. I vaguely remember a schematic I saw some 10-15 years ago or so. It may very well not work at all, it was a concept.
