Glad you showed this, HOLY _____ would be my personal response, I have heard about Enduron powder issues, Just wow
 
Luckily I only have 1# of the stuff same lot # as the OP's. It just turned nasty in the last 3 or 4 months. Sitting out back on a concrete slab until I burn the brush pile in back yard.

Watching the 4451 & it still looks OK.
 
Very noticeable.....unlike what gun powder normally smells like.....funny thing the actual powder looks normal....it is the cap that has disintegrated going to try and find some plastic caps for the other containers that I have
 
I have about 1/2 lb of 4451 left. Shoots very well in 6.5. Never knew it to cause problems like 4166 but I check it often. But wow, I would get that stuff out of my house. Looks like a science project went very wrong.

I opened all mine, about 12 pounds, seemed to smell decent? 3 of them were a touch stronger smelling. What’s the consensus? Throw it as far as you can and spray water on it or keep an eye on it?
