Aluminum foil powder bundle risk?

[Keyhole]

Hey guys, I saw in another post that there was a danger in having aluminum foil in contact with black powder over time. This is the first I’ve heard of this.

I have cannon loads for my golf ball cannon and a small .50 cannon that are made up in packets of aluminum foil. Most were made last year....is this a risk?

Keep them dry in a cool place and they will be fine. My aluminum foil loads of 500 grains of cannon powder shows no signs of degradation. These were made up in July 2021.
