Aged Powder

Getting back into the clays after being away for ~40years. Recently purchased all needed supplies to begin reloading again and found after going through my old supplies that I have ~1 pound of Dupont 700X from that era. Is it worth using or should I just dispose?

Depends. First, give it a good smell. It should have a healthy smell of Ether. Any pungent or acrid smell makes it garden food. Next...pour some out on a large piece of white paper. Swirl it around a bit before pouring it back into the container. Any significant smudges (especially red), toss it.

Unless you are 100% sure, it probably isn't worth it. Most 12 gauge powders are pretty economical these days.

If it passes the smell and visual check, shoot it up. I have rifle powder from the mid 90s I will start using up.

Thanks for the replies. Smell is pretty neutral not much smell at all. Seeings it's only ~1 pound I think I'll play it safe and fertilize the lawn.

700x seems to last forever if kept dry. I bought a 12# keg of 700x at an estate sale 2 years ago. It had never been opened. I have no idea how old it was, but it has'nt been packeged in 12# kegs in a looong time. I used it all and it performed flawlessly at what 700x is good for. Of course it left a lot of soot/ash in the barrels, but 700x has always been a dirty burning powder. My guess is that your odds of having usable powder are pretty good. Load, Shoot, Enjoy!

All powder keeps pretty much forever if kept dry and tightly capped. I've got powder and primers from the early 1970s that I use today and it's seen temperatures as low as -45 degrees fahrenheit in Alaska and +125 degrees or so here in Arizona.

Works fine.

I just finished reloading 100 rounds of 38 Spl with the very last of my WST. Last time I loaded with this can of powder was 1995. Will see how it does in a day or so.
