Did Oswald dry-fire his rifle in New Orleans using live ammo?

Are there any advantages to practicing the manipulation of the bolt that way?

I'm not sure. Maybe if you only had a small amount of bullets and you didn't want to waste any by firing bullets while practicing the working if the bolt action.

Why not practice working the bolt action without a round in the chamber?

To see how hard it is to chamber a round and then eject the "spent shell" by ejecting said complete round?

If you didn't use a round, then there would be nothing to jam the movement of the bolt action. I'd imagine the purpose of practicing the bolt action would be to prevent jams in a live rapid fire situation. So you'd need to use bullets of some sort.

That kind of practice will accustom you to how to effectively and quickly run the bolt. Especially if you aren't already familiar with the rifle. Different bolt action systems have a different feel to them. For instance, the Carcano action is cock-on-open design with a very aggressive primary extraction cam profile. Working the bolt on one feels very different than what you get using a cock-on-close design like an early Mauser or a Lee-Enfield.
