No, I did however consider it.
My downstairs flooded several years ago and the chest that I stored my ammo in was underwater for about 3-4 hrs (or so). It took a couple of days before I got a chance to go through my ammo and dry it out. I considered throwing it away but it was a lot of ammo so I figured I would try to salvage it (I did throw away all of the .22LR though).
I shot up all of my flood ammo over the next year or so and had 2 or 3 misfires out of a couple of thousand rnds of 9mm, 40S&W, .38spl, 357 Magnum, .308, 12 ga and 20 ga. I had a mix of everything from Silver Bear to Remington. I even had some reloads. It all went bang except possibly 3 rnds of Silver Bear in 9mm. Considering that I had a couple of cases that was underwater I don't consider this as a strike against this 9mm. Even the reloads made it through ok. I expect ammo to perform after being wet or even briefly submerged but I didn't expect such good results after hours of being underwater.
I did make sure that I was the only one shooting this stuff and it was all shot slow fire.
