A few months back a friend of mine had a flood in his basement. His hot water heater decided that it was time to explode in a spectacular fashion while everyone was at work.
After lots of cursing, and sloshing he eventually found the main water cut off. (BTW, If your water main valve is not clearly marked, stop reading this and go find it. Better now than when water is spraying.)
A few days later, after the hot water heater was fixed and the water back on, I was helping repack all their Christmas stuff in dry boxes.
One of the wet boxes had a ammo in it. It was about 30 boxes of .22LR that got soaked. He gave the ammo to me. So far it has been ok. Except for the cardboard boxes.
I had an idea so that would not ever happen to me.
I washed some 20 ounce bottles and dried them really well. Using a simple funnel I filled them with ammo. Each bottle holds 450 rounds of of 22LR. The pic shows a handy, grab and go, 900 rounds. each bottle is a great size, makes the ammo easy to inventory and keeps it dry. Six of them fit in a large ammo can.
I am going to buy some of the small desiccant packets to add. I may even test one in a bucket of water for a couple months.
