All will move forward. Elastic deformation and external forces on the
projectile produce a differential between the two objects. You can see the
effects on some of the Space Shuttle and Soyuz flight videos.

Just checking assumptions, please advise.
Am I right assuming a mercury droplet or loose ball-bearing will not move
forward inside a rocket in vacuum the instant the motor stops? It then only
might start floating.
Nor will such droplet move forward inside a cannon projectile after it
leaves the muzzle since on that instant push force has stopped. As to during
the short residence time inside barrel, it might fly forward I reckon.
