This is surplus military ammunition made in the Czech Republic. The ammuntion is packaged in galvanized steel "spam" cans which are then placed 2 to a painted wooden box. You are buying one can of 560 rounds, which contains 28 boxes of 20 rounds each. It has a full metal (copper) jacketed bullet with a lead core. Will not attract a magnet. The cartridge case is steel with a laquer coating to preserve it.
