I have no idea if FN ever used or when they stopped using corrosive priming. If you are to shoot this ammunition I would treat it as having corrosive priming and clean your rifle accordingly. I believe the US stopped using corrosive priming after 1952 but I would verify that date. Also notice this FN ammunition has no NATO mark on the headstamp.
The powder may not be corrosive BUT the primer almost for sure will be so like he said!I have no idea if FN ever used or when they stopped using corrosive priming.
