6 x 284 bad powder explosion

Sako pieces.jpgSako receiver threads.jpgSako arm damage.jpgNew old powder(H4831sc) first time use, after sitting on shelf for around 15 years. Didn't know what the powder suppose to look like, didn't smell it either(bad). Happened to a close friend of mine about 2 months ago. Many facial cuts and bruises, pierced both ear drums. Shot it out pickup drivers seat(left handed), shrapnel shattered passenger side window. Pulled bullets out of other loaded ammo, and bottle, powder looked like a combination of BL-C2 and pepper. Vortex did warranty the scope.
 
Thanks for posting. Always good to re-focus - helps to be aware of potential hazards.

The only time I ever saw a firearm blow up was during an NRA pistol match, center fire match, rapid fire stage. The guy next to me blew up a 1911, 45 ACP. It blew the magazine out, cracked the stocks in half, and bulged the barrel locking the slide. The only thing we could figure is that he had a squib load that lodged a bullet in the barrel but was enough to work the target action spring and he shot another round on top of it. No one was hurt but the custom 1911 was destroyed.

I have a bulged Barstow 1911 .45ACP barrel that this very thing happened to a shooting buddy during a USPSA match. Was definitely a squib, shooter "cleared" the gun and fired the follow up round before the RO could react and stop him.

DickE's buddy was very lucky, lots of shrapnel was flying around the cab of that truck.

Sorry for your friends injuries (he's lucky).
Why is he loading anything if he doesn't know
what the powder is supposed to look like.
It sounds like there was a combination of different powders in that ( NEW) powder jug, maybe it was at one time used as a "junk" jug and was never labeled as such. Maybe a combination of pistol/shotgun/rifle powders.

Sounds pretty much like a straight up case of wrong powder. I can't envision a case where 4831SC would break down to look like that.

That was SOME KIND of bomb, and he's a lucky guy to have not been tore up worse, or blinded. jd
 
So you're saying the powder was spherical, and with carbon dust? It might have been 4831SC at one point, but that's what you get with lots of hot & cold cycles and plenty of vibration, [ETA, like the vibratory tumbler affected it]. You'll see it in surplus powder, [ETA, though I've never seen kernel size so dramatically altered].

Stick powder burn characteristics can change drastically when you modify the kernel dimensions.

Or, if your friend bought it off someone else, he should be headed over there with an attitude.

I've seen a few rifles blow up and had a bit of an episode myself, but, THAT is the worst blow up I have ever seen. Damn---- Your friend is lucky to be alive. Glad Vortex warranted the scope but in the grand scope of things, (pun intended), who cares. Skin & bones are way more important.

was the bottle sealed? or did it still have a good seal??

that looks like a Sako receiver
 
Hope somebody can find out.
I'm no authority but if memory serves, 15 years ago (2009) was maybe about the time 4831SC was introduced.

My take on this incident has me suspicious of the labeled bottle being the original packaging; I still have propellants from before that date that show no signs of deterioration whatsoever (odd smell, change in coloration, change in appearance of particles) but I've stored them all very carefully since I acquired them.

I'd certainly look to Hodgdon for an answer as to the age of the bottle; at minimum, they might be interested in knowing more about the product inside which could be illuminating for all involved.
