This is a "wha's dis?" post I picked up some cases at the "range" last week and wondering what it is. The headstamp states "30-06 Springfield" and "MFS" in English then three other digits, not English. The cartridge has an indented "belt" near the case head, approx. .1" wide, which does not look like it is chamber marking/indentation, but manufactured in. Cases are steel, bright finish (possibly plated).The only info I found on line is the cases are either Hungarian or Nepalese. Any thoughts?
