Any idea what these finds are?

Two are clearly bullets, but I can't tell what kind. Maybe someone could tell me approximately what caliber they are? The third find baffles me. It looks like some kind of screw but I just don't know. I would also like to know the age if anyone knows.

What is it?

The odd screw thing looks like a needle valve from a carburetor or other fuel delivery device.
the others look like modern bullets by the looks of the crimps. Without measurements or something to reference too hard to tell what caliber.

Happy Hunting

Fuel mixture screw. Would have made a nice solid noise being brass.
