Thread on IMR 4166 decomposing

[P7M13]

If you have IMR Enduron powders, there's a very concerning thread over on accurate shooter.
I will be checking mine after posting this.

Aloha, Mark

Thanks for the post, very interesting read, starting from the first page. I'll need to check my 8 lb. bottle...outdoors of course!

I went and checked all my stock, both reading external temperature with a laser thermometer, and examining the seals of the jugs. There was little variance between the jugs and no seals looked bad.
My 4166 and 7977 were all fine. I need to use those next in loads. My Clays Universal has a yellowish tinge to some of the flakes, and has had that since I bought it -- it hasn't changed in six years.

I checked my 8+ lbs of IMR4166 and found it to be perfectly normal in look and smell.

Sticking with the old, tried and true powders seems to be the way to go. H1000 and H4350 have never given me a hiccup. I have a few lbs of IMR3031 I'm curious about now for grins and giggles

I just checked all my Enduron Powders (4166, 4451, 7977) they all look and smell fine. Maybe this was only an issue with certain batches?

I'll have to check mine now.

Thanks for posting this @P7M13 ! After reading all 9 pages of the linked thread, pretty scary. I don't have any of the 4166 that some are having issues with, but I do have some other Enduron powder that I'll be checking. I thought it was kind of strange that Hodgdon made all of that line go away quickly and fairly quietly. I could not find any mention of issues on their website (for these powders, anyway).

While looking, I did see that Hodgdon purchased RCBS from Vista Outdoors earlier this month.

I haven't been reloading as long as many here and only ran into one bad pound of powder in a box that was gifted to me. I can't remember what make it was but the powder turned a fuzzy green.
It got poured into a rotting tree stump but I didn't have the balls to touch it off since it was 20 from the house…

The oldest unopened powder I have was acquired about 4 years ago and don't know the year of manufacture. I still use it for 38/357 loads.

I have that can with about half lb of 2400 in it. Haven't tried it yet in .357mag though.

You have to remember that I load my 357's down so they shoot like stout 38's.

I remember back in the day (60s & 70s) the local gun shops sold surplus 4831 in brown paper bags. (eastern Idaho) i don't remember hearing of any problems.
