A Lee crimp die might work, but attempting to resize loaded ammo in a standard resizing die is going to result in a stuck case. When a case is resized, the neck is squeezed down slightly smaller than the bullet diameter so that when a bullet is seated, it is gripped tightly by the neck. After the bullet is seated, the case neck is now expanded slightly larger than the sizer die. A loaded round can probably be forced into the die, but it will then become a more or less permanent part of the die.
