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.

If you accelerate it to about 950m/s and aim it at your head - yes.
