Anybody ever had a Powder Explosion?

I have about 5 pounds of 4166. I have checked it looks and smells fine. But due to a recent personal experience with a house fire, I think I will be very cautious and take it out and burn it. Not worth the chance.
Sunday night/Monday morning, 5-13-2024, the home that I grew up in caught fire and is a 100% total loss.
The really hard part is that I lost my only child (son) in the fire. The last 10 or so days have really been rough.
I cannot imagine your pain. My heart felt condolences and prayers to you and you family.
 
ok just spent an hour digging to the very rear of the storage shed getting the powder out. theres parts from 3 cars in there, just about everything but the body. One jug was bought in 1993, and the other in 1996. both IMR in the old square metal cans. It went bad about 2000 when i opened it, rusty brown color and smells bad. I put it in the shed thinking bad powder is better than no powder if the SHTF. enough stories her to worry me. its been in the shed for over 20 years, and the shed sits in the sun, buttttt,,,,,, still is rusty brown and smells different just like it was years ago.

I am so sorry. I cannot imagine how you're feeling. It makes our troubles seem miniscule.
 
Not a powder explosion. But my uncle lost his house to a fire. He is obsessed with cleaning his guns and they stacked a few different rags with gun cleaning chemicals and woke up to their house half engulfed in fire.
He lost a good 20+ guns including a custom hall rifle and a remington 40x700 factory gun with a 1.25" barrell. Step son was last one in gun room cleaning. Uncle was flewn out to hospital with nasty burns saving his step son. Ended up having to have cadaver skin grafted to both feet form melted plastic carpet burns. Long a bunch of leupold lr scopes. Was never able to get insurance to cover the fire. Never recovered from his loss.
 
If I'm reading this thread correctly. All the problems have occured during exposure to excessive heat? Be it sun or air temp?
My experience was the powder was stored in good conditions, and suddenly went bad at about 4 years old, with no good explanation. There was no exposure to excess heat. I disposed the remnants immediately when I realized that the powder was bad.
 
Just checked my 1# 4166 from 2020 in response to this thread. It looked normal, but smelled terrible. First time I've had powder turn bad. I can still taste that smell 20 minutes later.
 
More likely gassing off and just building enough pressure to blow the lid, not really anything actually combusting...
So the video was faked? Pretty good, even had the guy ducking for cover. Maybe he was edited in as well....

Thanks for the heads up, @DLT I'm checking all of mine today. Glad it wasn't worse.

Im the star or the star idiot of this show. Wasn’t any editing going other than when they sent it to me from work that evening it was slow motion. When played full speed you could hardly see the fire ball is what I was told. I’m going to get the full speed video when I get a chance. Here is another one I took once I gathered my marbles and figured out what exactly had happened

I don't doubt that it happened just like you said and hope you didn't take my comment seriously. I'm glad that nothing else happened when it went off. Once in a million maybe, but I've never liked those odds........
 
I have to wonder....
Some guys here mention powders they've had for many years without issue and here we're talking about "new and improved" powders with copper fouling reducers and various other changes, supposedly to make it better.
The old adage: if it ain't broke, don't screw with it just may apply here.

Trying to learn something here. Do you think the smell of the powder you checked today changed a lot from when it was new?

Could be right as to why. But I got a fireball on camera let me try and post a link. Was not just pressure building as popping lid. WATCH THIS


Watch this !!!
I like the way the powder flashes upward and you briefly flinch then, saunter over to it.
If that was me, I would have dropped to the deck then looked for a fire extinguisher then looked for a fresh pair of underwear.

DLT, l went back and reread your first post. When you first found the bottle with the sticky lid that was stored normally, do you think it had excessive heat?
Just curious because someone else had mentioned one of the temperature detectors, and I think they can be purchased fairly cheap at someplace like harbor freight.

This post strikes a chord with me. In the old days when life was simple, about half dozen of IMR powders left nothing to be desired. I still remember those metal cans and the feel of them.

There was always an ample supply at local shops. You didn't need to stock powders because they always had them. Of course, a lot of us were not affluent and couldn't afford to do that anyway. I would keep two cans of the ones I used. When one can was exhausted, I just go to the local shop and buy another. No shipping - no hazmat - no wait - no panic buying.

Today we have made reloading, cleaning, and shooting into a complex mystical process. The sellers of commodities that support this complexity mindset must love it.
