In Korea in the late 90's we routinly used Powder for our 155's from 1944. Shot just fine...weird smell. I also blew 25lb shape charges from 1943. Worked perfectly, but the carrying strap had disintigrated.
The PSA CEO is a pretty hardcore 2nd Amendment guy.
In the near future, the only thing that PSA isn't going to make is their own powder, they will be making bullets, brass and primers.
I don't know if their long-term plans include buying a copper mine, but I wouldn't put it past them.
I store my ammo like the army, in a steel ammo can, with some dessicant, and since I'm crazy, I tape a humidity indicator card to the inside top.
Humidity is what kills ammo, not temperature.
My former local radio station has a firearms show too, that's pretty good. Different vibe, Dicks a former Ford exec and all around great guy. https://www.triggertalkradio.com/
