I agree with everyone, that IS a bomb waiting to go off.
Several years ago I purchased a Government surplus mortar can. It’s taller than a 50 cal can. I purchased one that looked new with a good seal. I store all my primers in it.
I keep a Remington dehumidifier in the can and in all my safes. The nice thing about it is when the small window turns pink you plug it in to 110 and in 3 to 4 hours it’s like new again.
