I got them in a buy out awhile back an old fella in his 90s had them. I have some old norma an imr cans that are probably 60-70 years old and full of powderThose old school Federal 215's looks like the belong in a museum!! Those packages advertise that they are non-corrosive....I thought that all primers have been non-corrosive for over 30years. Seriously, those are a cool display piece for a man cave.
