Too much nonsense posted in many of the replies so far to cover in less than 20 pages.
I'll adress one. There have been many tests proving static electricity will not set off black powder. Googling will confirm that.
I have been an avid, and active, muzzle loader for over 40 years. In the 1970's I had a gun shop specializing in muzzle loaders and sold black powder. During that period there was an interruption in supply and bp was hard to get. I bought some in metal (plastic bag lined) 25 lb. canisters.
For resale I weighed out 1 lb. worth into freezer boxes. There were cardboard with plastic bag liners. Worked fine.
Handling bp is not the demon the uninformed make it out to be. Common sense certainly needs to be applied.
