Does anyone recognize this brass I picked up? I was able to look up the one starting with 'MEN'. My search said it's German 7.62 NATO, but I can't find anything on the other, starting with 'DAG'. I know it's more .308 and I'm assuming it's also NATO brass, but I can't find it anywhere and I was wondering if y'all had ever seen it and what the difference is between the two, if any.
