I stand corrected!
According to
Firearms History, Technology & Development: Corrosive Ammunition
"the US Army switched to using potassium chlorate primers in 1898."
This article also has a simple method to test whether you have those corrosive primers.
BTW The commercial 30USA cases I have weigh quite a bit more than the commercial 30-40 ones.
It's not just the military brass.
