I've been trying to use up old powder I've had for quite some time. Here's some I've had in the back of the powder magazine for a decade and a half, and it was pretty old when I got it. Notice the price tags: $1.88 per pound.
I'm thinking I'll see if I can work up a usable load in .300 Win Mag with some 200 gr bullets I've also had laying around, though from what I've been able to find for data it looks a bit slow for anything that I have.
Anyone ever use it?
