thought i found "gold"... well at least nickel.
bunch of shiny 7.62X54R.
sad they are berdan primed, and just a short cleaning in corn cob and the shinny is all gone.
looked real good when picked up. but just all junk.
if the coating had been good might have converted then to boxer.
head stamp 7.62X54R MFS and what looks like a ("6"), (upside down U but squared off), ( a "3" with a long leged base going to the left).
