Would you use ammo that was inundated in a flood?

Well, I had a hundred-year flood in my rural neighborhood and one of my ammo storage areas got flooded. Several hundred rounds each of .40 S&W, .223 Remington, and 12 ga., all factory new. The flood was clean rain water that fully immersed the stuff for 12+ hours before I got back and got it out of the water.

My first thought was, "well, it's all ruined, I'll have to throw it away." So, how do I throw it away? In the regular trash? What if it's not ruined -- is there a regulatory problem with throwing away good ammo?

But all the ammo, now that I've got it in a dry room drying it out, looks to be in perfect condition. None of it looks corroded. Should I keep it, label it "water damage?" and try shooting it later?

I called 3 local gun stores. One guy said the ammo is ruined. Another said it's "probably bad". The third said, "you can probably shoot it."

What is the worst that can happen if I keep it all and try shooting it? If it shoots, great. If a couple rounds in a batch don't shoot, throw the batch out. But what if a round only goes half way down the barrel? Then if I don't catch this problem perfectly each time it happens, I risk blowing up the gun. So what to do?

Maybe test it by batch? For example, most of the ammo was in cardboard factory boxes. But some of the ammo at the top was in sealed plastic bags. Since it was at the top, it got less exposure to water. There's a little water inside the sealed bag but not a lot. So maybe some of the ammo is less compromised than the rest. Should I track that too? This could be a major project.

This is several hundred dollars worth of ammo. Do I claim it on homeowners insurance, or is that not worth the hassle and higher future rates? I'm probably not going to submit claims for anything else to the insurance company.

Any advice?
 
+1 for the GI ammo cans. Also, something to be said for keeping stuff like that above the flood plain.

I dont think there is much profit in messing with that stuff. Give it the heave-ho and start over.
 
So get a bullet puller and dissemble a few test rounds, if they appear dry inside, then test fire a few and see what happens next, just beware of any squibs.
 
soldiers wad through water...though not for 12 hours.
mark it as 'drowned ammo' and use your guns to throw it away--slow fire.
good crimps = good ammo. as for the primers, you will know when you try them.
+1 Sheldon......and as long as its apart, test the primer (in your gun). good luck
 
Ditto the above - I'd pull a few rounds, check the powder, and if it was dry, I'd pour it out in the back yard and load the shell into an appropriate gun and see if the primer will pop. If it goes bang - I'm shooting the rest of the ammo. :)
 
I'd second all the suggestions that you check to see if water has gotten into the cartridges.
Here's a link to a bullet puller from Midway:

If water has gotten into some of the cartridges don't bother trying to shoot them. Pull all the bullets and realize you've got a GREAT reason to start reloading.
If they look ok and if you try shooting them I think you'd notice, from the noise, smoke and recoil if the bullet doesn't exit the barrel or the shotgun shells give you a squib load. That said, you're putting a few hundred dollars of ammunition against expensive guns and a possible safety hazard.
 
No need to pull it.
Just try shooting it slow-fire.

If you get mis-fires or squibs, then you'll know.

It will not hurt anything in the least, as long as you are aware that you might get some squibs and stick a bullet in the barrel.

I agree with the above. Pull a few bullets, look at the powder and try to see if it's wet. Test the primers too and make sure they work. If they do, you're fine.

If you really want to get technical and be extra sure, buy some cobalt chloride strips and dump the powder from one cartridge along with a strip in a dry plastic baggie.... shake and if it. If it reacts and changes to pink, there is water.... if not, repeat with another 1 or 2 cartridges... if everything is dry, you're fine.

If you have a squib, all you have to do is push the bullet out with a wooden dowel rod. If you start having some duds I'd think about taking the ammo apart for components. Even if you don't reload, you could sell the components, assuming there is no water corrosion.

Ammo is usually sealed pretty tight enough to shake off water for awhile. If your ammo fails to shoot properly or reliably i'd either take all the ammo apart and sell everything or just sell it as water damaged ammo and someone else will probably take it apart the same.
 
Anybody ever leave a round or two in their jeans and then run them through the washer? Dryer, too?
I done did that a few times and the rounds always worked fine. And they weren't even factory, but reloads.
 
I wouldn't make a insurance claim unless it's $10,000+ dollars in damage.

It's just not worth it in future fees.
 
Someone from my church recently gave me a bunch of ammo recovered from a mudslide a couple of years ago. It was mostly still in falling-apart boxes, but was filthy. I cleaned it up. The military ammo ("DEN 42" yes, I know it's corrosive) with its sealed bullets and primers I'm sure is OK. There was also some commercial ammo, and I pulled the bullets from a couple of the most corroded rounds and the powder was still just fine.

I intend to shoot all of it except the ones with badly corroded brass.
 
i've seen ammo (mil-surp, so take with grain of salt) submerged for 24 hours and shoot fine. but dont take my word for it with factory ammo. and i dont think shotgun ammo is watterproof anyhow. so i'd pull afew and see.
 
Testing the water-damaged ammo

Water-Damage-Man here again. Thank you all for the feedback. 20+ replies in an afternoon -- what could be better than that!

I tried shooting sample cartridges of the .40 S&W ammo that had been fully submerged in floodwater for 12+ hours this afternoon with the following results:

I fired 10 rounds, each taken from a different box of ammo. 7 rounds fired normally. 2 were duds. And 1 fired but the slide (on a full size Glock) failed to cycle and the empty case remained inside the chamber.

If you extrapolate from the sample, that means that the ammo in general is ~70% good (which is higher than I expected).

Brands that worked included Winchester FMJ, Independence FMJ, and Remington JHP. Brands that didn't work included Winchester BEB and Remington JHP. The brand that fired but didn't cycle the slide was Federal FMJ.

I have not yet tried the .223 or the 12 ga. ammo.

To be safe, I've decided to fire all of this ammo without the use of a magazine (at least until I understand the results of water damage on ammo better). This forces me to load each round in the chamber by hand, it slows me down, and it makes sure that I notice any squib rounds before I pull the trigger again.

I'm also going to get a bullet puller, as suggested in this thread. And I'm working out how to make sure this doesn't happen again through a combination of storing up higher and with watertight ammo cans, both as suggested in this thread (the problem is a lack of good space).

Would love to get further feedback from you all on this. I'll let you know how shooting the .223 and 12 ga. ammo goes. The 12 ga. has started showing a little corrosion on the outside where the primer cap is -- that can't be good. But none of the .40 or .223 is showing any corrosion or ill effects on the outside.
 
During waterfowl season the boat we use gets a lot of water from the dog, rain, and us getting in and out of the boat. The 2 pits we hunt usually have 2-3 inches of water in the "sump" we stand on a raised platform. Every year we drop a "few" shells that we do not find till someone starts to run low and starts to lift the platform boards or swish around the bottom of the boat looking for shells. Some shells in the pit have weeks under water and they still shoot. Of course waterfowl loads are marked waterproof. I have washed many of .45 rounds that later shot fine. Until you try don't throw them away or pull them apart.

Be careful single-loading ammunition in a semi-auto. Pistols are *not* normally designed to happily digest cartridges dropped into the chamber and snapping the slide closed over it. It's *very* rough on the extractor. If you insist on single-loading, use the magazine to chamber a round and then remove the magazine.
