another clue to help date my site

[jerseyben]

I have another thread open right now asking to help date a site I am currently working.

Here is another item pulled out of the site. I have NO CLUE what it is or how old it is.
First guess is a really old shotgun shell. But why would a shotgun shell be ornately decorated?

Possibly a lipstick tube?

And now they are made of plastic..... no character.
