There are cases of US civil war collectors having 150 year old powder loaded cannon balls exploding and killing them while cleaning the balls with wire brushes
I do not think black powder degrades and becomes more sensitive with time but will happily take a correction

Google civil war collector dies cleaning cannon ball

and you should find the story
Keep we'll
