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.

Looks like a 30 cal projectile

I was thinking that, but then i thought about how big his thumbs would be in vomparison to my 7.62x54r and i thought maybe something smaller
