No, but your hinting at a truth...

When non-ferromagnetic material that is conductive moves through a field it is true eddy currents for and opposing magnetic fields form... However these fields would never cause the bullet to change its course, it would only cause the bullet to slow down. So it will not behave as you'd exect a magnetic material to behave.

In fact you can slow something down to such an exctent it will levitate freely above the magnet (if the magnet is the thing moving, such as a spinning magnet). Which further demonstrates it is not attracted tot he magnetic field but rather opposes it (in this case pushing away from the field.).

In other words the attractions and repulsion will only be enough to counter another force, and not enough to "move" the metal on its own in a direction contrary to its trajectory.

So yea, while seems you get the basic idea already its important to note the only real effect would be to slow down the bullet a bit and hit it up.

And yea the heating of the barrel would demagnatize it but I doubt my barrel is going to get anywhere near steels curie point.
