For long term storage, you might need a dessicant. Depending on how much ammo you want to store, you will need more than just a few little packs. The
neat thing about silica gel dessicant, is that it can be re-used. and here's a tip from another buddy on how to get all the dessicant you'll ever
need!!!!

Go to a japanese motorcycle dealership and find the builder. He's the guy who assembles the new bikes when they arrive in the crates. Each one of
those crates has a five pound bag of silica gel inside. They're thrown away with the crate. I ususally trade a case of beer for all the silica gel I
can carry away. Cut the bag open and spread it out on a cookie sheet. Bake it at about 200 degrees. Break the lumps up as it dries but be carefull of
the steam coming out of it. When it first comes out of the bag (Used) it's kind of gray and lumpy. As it dries, it will turn back into white
crystals. Store it in airtight jars until you use it.
Was a great tip Big thanks to Mac
