Suppose you fell out of your fishing boat and swam to shore. Would most pistol ammo be good to go?
Super-Dave,
Here is a test for you to perform. Get a bottle of water, some ammo and a plastic bowl. Go to the range. Pour the water in the plastic bowl now drop a handful of ammo in the water in the bowl. Let it sit their some. After 10 minutes in the drink pull a few rounds out and shoot them. How do they work?
Now wait 20 minutes and take a few more out. Shoot them. How do they work?
Now take out a magazine (Modern Bride, Woodworking Today or such) and sit down and read some. Let the rounds soak. (Ignore those people around you at the range wondering why a man is at the range sitting on the floor reading Highlights Magazine with his bullets in a bowl of water, you are involved in the higher calling of science and they are irrelevant.) In an hour or two shoot off a few more. Do they work?
You can mix it up some, try soaking the bullets in some chicken noodle soup, motor oil (if you live by the Gulf you could fall outa boat and into that, it's possible), etc. I'd avoid any liquid likely to burst aflame you do want to avoid any Super Dave Osborne problems.

At any rate try a few experiments to find the answers you are looking for.
Simple thing though, if you are really worried about this would be a plastic bag as has been suggested.
I am making fun, but not of you. )
