It's not really surplus ammo, but it certainly works in plenty of surplus and military-style rifles.
Here's a few pics of some ammo I just received. Prior to this batch, the "newest" Chinese ammo I've seen in Canada has been mid-90's production. It's advertised as steel core, but I haven't sectioned any to confirm.
Factory 311 on the headstamp (though the "fun fact sheet" say Factory 941), packed 20 rounds to a box, 30 boxes to a plastic bag, 2 bags to a cardboard case of 1200.
