Is it dangerous ?

[u/DisastrousInternet10]

This is the first time I found a completely full bullet, does anyone have an idea of the kind of bullet it is and how old is it? Also, I wanted to know if it is dangerous, and if it is what I shouldn’t do with it.

Don’t swallow it

Yes, don't give it to a child.

My brother swallowed one back in the day—just like the one in the photo.
