dude.  we all should be saving copper to melt/plate layer the cones for shaped charges. if everyone in usa hordes ar-15s then we know from current ukraine battles that as 2nd amendment valuers we all should stockpile legal copper shaped charges sleeves. there's no argument against this. you can make them without metal casting experience with a battery and copper to plate it over and over until adequet thickens (it takes 12 hours per 55mm cone)
