You can search the net for specifics, but most DOD ammo used corrosive primers/powders into the sixties.
Again, this is not a problem if you clean your weapons after a firing session - the “corrosive” nature of the components is not a problem to the ammo itself if storage conditions are adequate.
Most military ammo was built to withstand temperature and moisture storage extremes that commercial ammo just can’t tolerate. I have fired thousands of WWII rounds without the slightest problem.
I still have several boxes of Italian 7.35mm military rifle ammo marked 1939 that fires every time. I wish I had bought more of it decades ago because it isn't available anymore and the old rifle still shoots well.
I could buy Lee dies for it and make brass out of Norma 6.5 Italian cases, but I would have to cast lead bullets for it if Lyman still makes the molds for it and reduce the powder charge down for a low velocity load. But that's a lot of expense and trouble just to shoot an old rifle at plastic Pepsi bottles and soup cans.
