I know this post is dead, but I feel my story is worth sharing. I'm an avid reloaded. I have been for almost 15 years. In that time I have never sealed a primer or a bullet. One Christmas season, we had a large rainstorm that flooded part of the house and everything in the lower garage, including all of my ammo. My ammo was stored in cardboard boxes (the kind from midway), inside a wooden ammo crate. All of my loaded ammo was under water for over 6 hours. It then sat in wet boxes for 2 days (I had a bigger problem to deal with). I then pulled every round out, laid them out on a towl and dried them with a couple of fans for the next couple of days.
1 week later, believing all of my rounds were ruined, I decided to take my son in law to the range and see what would work. I am talking 1k+ of each 223, 9mm,40 s&w, 45 acp, 2k of 22 LR, and hundreds of rounds of 30-30, 30-06, 357, 308, and 12 ga. Every single round fired, including the crummy 22lr (the bullets would actualy spin in the case mouth). It was a fun day, but now that my entire surplus was blown, I had some serious reloading to do.
In the end, I'm happy that every round fired, but in hind sight I wish I had kept it all.
And all of my ammo is stored in ammo cans off the floor now, btw.
