Can we have some dimensions? Not sure its a bullet though. Is the end piece plastic?

Doesn't look like any wwII bullet I've ever seen. Pretty sure it is something else than a bullet.

The end is a piece of plastic that comes off.
Circumference around the metal part is 2 inches, length of metal piece is 1.75 inches, the diameter of the plastic piece is .5"

I just added some additional pictures.

Thank you for your help!

It's not a bullet, but I have no idea what it could be.........!

Im not 100% sure its ww2 related first thoughts were it could be a battery but the plastic does'nt relate either then i thought that the plastic end piece looked like a press stud but still no ideas

Doesn't look like a bullet to me. Why would there be a plastic bit on the end??? Just a 'thing' in my opinion.

Old battery?

An old camera shutter button that used to be on a long wire?
