Just got my hands on 3lb of DuPont SR-4756 (Lime Green Print Can) and a pound of DuPont SR-7625 (Gray-Blue Print Can), They are obviously metal cans. I know it ran under IMR for a while I think before discontinued, but the cans were unopened and appears to have been kept dry and sealed, anyone out there know how old these may be? I got along with some other goodies from a friend of mine, couple cans of GOEX FFFFg and a can of Pyrodex CTG (These look a little worse for wear). Haven't gotten my hands on them yet, I will see him this weekend so don't know what powder looks or smells like but they were free along with the other stuff I got.

That stuff was being sold new in shops in the 80's and the old metal can powders work just fine for me. (IMR 4895, IMR 4350, IMR 4064, SR 7625, and even some PB yeah most of my stuff is old, been opened and stored in my basement and the last time I used the 7625 all was well, and the 4350 too (about a year ago).
If it looks good and smells right (and the inside of the can isn't all rusted out) use it and be grateful you have it.

As a high school graduation present from some of my shooting buddies, I received a couple of "cans" of Ball C: approximately 25 pounds apiece. Back then it was a forty-year-old treasure. It has only been a year or two since I finished shooting up the last of this now-75 year old powder. I routinely shoot powder from the '70s and '80s. In my "working" powder stash, I have small metal cans of Unique, Bullseye, AL7, and a tiny bit of 2400.
As Rick H. wrote, if it looks good and smells right, and the inside of the can isn't rusted, I use it.

Thanks guys, I appreciate it, Picking up on way home from work today along with a big stash of primers, 209's LR, SR, LP but still no small pistol. going to have to find someone to trade with I guess, now I got way more large rifle and large pistol and shotgun than I need but was a package deal.
I haven't seen those cans for a long time. H-570 was my childhood mentor's preferred powder for his beloved 7x61 S&H; I used in my '06 Ackley for a time before trying other powders. Check Speer #6 and contemporaries for load data. My notes say that was the source of my starting loads for the Ackley back in the late '70s.
Exactly same type of cans I got, all seemed good, 1 smelled brand new, the others not to much smell left but passed the old spark test
