Thanks for the input, but I can't have my family learn that they are live or they'll freak. I need to either make safe or dispose. 5.56 sounds about right. I am near Clifton, NJ and the local gunshops can't/won't help.
I have three rounds from an Army SAW that were gifted to me. I would like to display them but can't find anyone who can/will make them safe. Any ideas?
