Are you joking? "An unexploaded bullet" Your not talking a bomb here.......throw it in the freakin trash............or maybe......just maybe..... you could call the bomb/bullet disposal team from Washington and they could take a close look at it
Sorry I don't know what the Laws are in Bulgaria, or even if your talking Very Old or
recent .
In most cases here in the U.s. we just keep as is, Or throw away bullets.
I don't want to tell you this, IF you can be arrested for the same so
Perhaps if you can describe it , If it says anything on the Bottom ?
if you can supply pics ?
you can always dig a hole where you feel Comfortable you won't dig again,
and rebury it, Or even bury it at a depth you can just bairly hear it on your detector.
Then use it as a test signal on occasion.
What do you mean by bullet? Is it something that fires in a rifle or pistol, do nothing.....if it is something that fires out of a RPG, genade, or cannon/artilery shell....post a picture and perhaps we can help you.........
