I've got a quanity of 8mm ammo, and was wondereing if it is corrosive primed. The first headstamp is FNM 70-25. It's berden primed. I think it is Portugese. The other is headstamped 7.92 MM 44. These are boxer primed and I was told they were canadian produced. Are these both corrosive and why did canada produce 8mm if in fact it is canadian?
