I believe there have been other lot(s) that were reclassified "Not For Duty Use" as well. I was thinking of ones with the blackened G2 bullet for some reason. Those would have the brass primers. I, personally, would not buy any loose ammo in a can whose history and lot numbers could not be verified, especially for defensive use. Just because it "works" in someone's gun doesn't mean it is suitable for defensive use and does not have other latent issues. It was reclassified "Not For Duty Use" for a reason. I have found it difficult, if not impossible, to get the real scoop on "overrun" or "Reclassified" ammo from the manufacturer (any manufacturer), and doubt I fully trust what a rep from the vendor (any vendor) says that is trying to sell the ammo.
Hmmm…
My duty ammo recently issued by DHS is nickel-plated brass with nickel colored primers. It came in a factory box with lot number on the inside flap.
The ammo I bought loose in a metal ammo can looks exactly the same. I’m not saying it’s identical in function, but it’s visually indistinguishable from the issued ammo.
So not sure that nickel primers are a reliable indicator of “old, recalled” ammo, unless DHS didn’t check the recall and issued it anyway.
