I had a situation where the guy installing my furnace didn't finish the job and left a dirty water discharge line hanging freely above a couple of storage boxes – where factory ammo and primed cases were stored.

This led to many valuable factory centerfire cartridges and primed cases being immersed under some really dirty brown water for several weeks – before this freak situation was discovered. As some of you may know, reloading components – and even certain types of factory ammo – are currently in short supply, so this involved more than a financial loss.

I air dried the wet cartridges and threw away the many waterlogged factory ammo boxes – then tumbled the grubby, tarnished, sometimes hard water encrusted cases. To my surprise, the majority of the rimfire ammo seemed to still fire. The centerfire stuff was a different story.

Some handloads were Okay – as was a quantity of the Russian surplus fodder – which had been made with that that black bullet and primer sealing compound. What was left was really unpleasant to even test because shooting the damaged stuff involved random duds, potentially-dangerous squibs, and some nasty hang fires. I was glad to not have had to share the range with anyone that day.

I found that, if a weighed a given lot that had been immersed, I could find the heaviest rounds and then thereby generally establish the individual cartridges most likely to have taken-in water. Then, I took these sample test cartridges for that lot apart. This method helped me to figure-out which groups of ammo were flooded and need to be taken apart and dried-out. As much as possible, I used an RCBS bullet puller – using one of those kinetic bullet pullets only where I couldn’t get the right collet, or the ammo didn’t permit the use of the RCBS puller.

The water-logged powder – coming from the cases – often was a dark, paste like substance. However, after this was air dried, it looked and worked like new. I keep notes of my reloading, so in the case of my handloads, I was able to IDENTIFY and reuse the powder. At first, I left the primed cases to air dry, but I found that only about half of these worked. I decide that if was likely that the primers can’t dry-out sufficiently, unless they are removed from the primer pockets. I did this with a Lee decamping die, and I examined the recovered the primers.

About 30% of these seemed to have been damaged by that removal method – often with the anvils separated from the cup – due to the freefall trip these had made, after decapping. I switched to a Franklin Arsenal “Ultimate” hand decapping tool – and this was a tidy way to remove and non-destructively recover primers. I discarded the primers that looked like they were too fouled, by the dirty water (say, 3% of the total) and – after air drying – reseated the remainder.

About 98% of the recovery effort resulted in perfectly good, restored centerfire ammo. About 1% of the recovered primers developed small blow out holes. I don’t know whether that was due to the extra stresses on the cup metal from the removal and reseating process, or whether these primers were already bad. Apparently, there was a bad lot of Winchester primers, that exhibited this problem.

The bottom line is you can recover and reuse power primers, brass and bullets from totally-soaked ammo. Was it worth it? Yes. Was if fun? … NO!

Will I ever hire that furnace installation firm again? Not likely.
 
It's stories like this that I use to justify having all my ammo in metal ammo cans. The only exception is shotshells, but they are at least stored on upside down spam cans to keep them 6" off the floor in case of a small leak/flood situation

I agree but it is only as good as it's seal.

You can find non-surplus ones with a nice gasket to seal it in but some older ones don't seal up properly. Wear and tear can add up
 
I’ll tell you what I would do not what you should do
Pull the suspect bullets, then you can tell if powder is dry If it is dry (I mean totally) pour into a container If it’s wet so is your primer
Rinse wet primed cases to clean powder I would deprime asap so brass does not corrode making primers hard to remove
Inspect primers for damage (discard any that look bad) put primers on a metal tray & leave on a warm not hot floor register till you are satisfied they are dry
Wear safety glasses
Projectiles should be ok if not corroded, wet powder pooched,
Try a few reloads with components go slow
Price of everything these days worth a shot for practice rounds
Again only what I would try
 
There are always those on CGN who are overly cautious. No "your wet powder" ISN'T "pooched". I have first hand experience to the contrary. Besides that, in the manufacture and distribution of powder they actually intentionally wet it (with water) to make it safer to handle and store.

Why not shotshells?

Simply because I've gone with all 30 calibre sized cans (minus a few exceptions) since they are more convenient for weight to carry a full can to the range. I try to keep ~2-3 flats of shotshells at any one time on hand, and if I remember correctly even in 50 cal sized cans you can only fit 6 or 7 of the boxes inside so I don't have enough currently. I also like keeping an exact inventory number of how many rounds I have (thanks OCD lol) so I can't even entertain the idea of bulk dumping the shotshells into ammo cans (it would lead to me having to dump them out and count them after each range trip :p )
 
Before I did anything, I would have taken lots of pictures, phoned the company, boss, and tell him what happened and what are you going to do?
Not pay for the service would be a start. Figure out cost to replace, and send that into the Co. Now it is a one man working out of his truck? could be a uphill battle.
Daughter is going to have a 6k bill because of idiots that don't know how to install furnaces. , same thing water running wrong direction.

That's good to know. Thanks
 
About the only component I'd have concerns about is the powder - not because of its contact with water, but in changes to the shapes or damage to the coatings from the handling of wet powder. Extruded powder forms and coatings on the ball powders work to control the burn rate. Was this a ball powder that you were able to re-use?
 
I did some research before I reused the powder. I learned that the powder manufacturers themselves intentionally wet-down powders during manufacturing, processing and maybe transportation - as a safety measure. I'm sure that they wouldn't deo that if it was determined that this damaged the product.

The stuff that I extracted was like a dark paste and - in fact - it was hard to get it all out of the case. I generally got as much out as I could and then left the residual - still in the case - to dry for a day or so until the rest was ready to fall out, on its own.

I put the stuff in a stainless bowl and stirred it a bit to let the powder air dry more. The power dried very quickly, to me indicating that the wetting was on the surface of the grains - not absorbed at all into the grains. After the quite short drying time, I compared the dried out, previously wet powder to some from the same lot that had never been wet - and there was no apparent difference, in any way. Yes, the grains had exactly the same size, shape, colour and texture as before.

I considered the possibility that the quality of the powder could have been harmed from the dirty material that had been in the filthy water. However, I loaded the ammo up in the same cases and the same primers (which I had also dried out) and everything shot as normal.

The only loss was the time spent. I also had a small number of primers that I threw out because they looked full of residual gunge. I also had one hang fire, in about 200 rounds - definitely because of the primer involved - not the powder.

BTW if anyone is confused about this they may be thinking that balck powder and smokeless powder are equally susceptible to water damage. From what I've read, this isn't so. You can't dry out black powder and expect it to work whereas, with the smokeless stuff, it is "no problemo"

Read about the German recovery of ammo from the Kronborg in WWI. It was disassembled, dried and reloaded.
 
I had a similar but worse outcome experience when I had to empty an old shooter's workshop. He had some old refrigerators buried under the floor and used them as storage "traps". There was ammo stored under the floors, on wood and concrete floors, and in cabinets.

If the ammo was in paper packaging and not up away from the floor - forget it! All the paper was flakey and/or stuck to the rounds. If in wooden boxes - probably good, except for paper which would have been exposed to higher humidity. Metal ammo cans were generally reliable storage, except if the steel touched gravel or concrete. I lifted more than a few cans where the bottoms were rusted out. They are moisture proof, not waterproof. Ironically, he had other ammo in old refrigerators on the racks. That stuff was more deteriorated by humidity (trapped I suppose) than boxes stored in shelving and drawers where the air flow was natural.

As I sorted ammo it went into KFC chicken buckets for keep, p1ss away as blaster ammo, sell, salvage components or leave at the nearest military range amnesty box. For the latter, I would deliver heavy gauge plastic bags that were just about as heavy as I could carry with one-hand. "I have no live rounds or empty casings in my possession, Sir!"
 
The furnace installation company has insurance

You also could of filed a claim for negligence

Wouldn't cost you a dime and would be paid out in cash or purchase all new ammo and components

They probably would of let you keep that damaged stuff too

Sorry this happened I'd be very saddened and disgusted

Glad you got to savage so much

in the home manufacture of the Holy Black, the material is soaked to a paste, then either screened to granularize, or compressed to bricks which are broken into small pieces later.

I believe commercial BP is also made wet

due to the shortage of BP, I'm going to try to salvage BP from fireworks and soak it to a paste, then screen it.... it may not be of highest quality, but it should go "BANG"
