Winc. USA '99 " headstamped 5.56 was Very hot, as in , needessly high pressure. Just an FYI, only fire those in 5.56 chambered firearms. And it isn't corrosive.
I agree. Not corrosive
I don't ever recall seeing anything about any 5.56/223 being corrosive and would only be carefull if I came across any odd brands made in

Another vote for not corrosive.
