wet/humid 7.62x39 ammo

Some people have tumbled loaded rounds to clean off corrosion or verdigris.

Other people say doing so may "powder" the propellant to an extent that will increase the speed of combustion and loading to a potentially dangerous extent.

I think a short tumble will be fine. I wouldn't do it for hours though.
 
Youre still not making sense.

Thanks to everybody else though! I knew there'd be some guys out there who have experienced some nasties. After sorting through it all I feel pretty good about it. The bullets have a heavy ring of purple sealant around the neck and primer. Plus they have a shiny (lacquer?) coating thats thicker than any other ammo I have.

I guess I wont know for sure until I shoot some of it.

Lol.

As an occasional internet troll myself, this made me laugh.
 
A case of 7.62x39 is likely WP or Chinese lacquered steel cases with sealed primers. The paper will stick to the finish, and maybe leave some discoloration. But, unless the ammo was under pressure, normal peasant proof ammo should display no lasting effects. I cleared an old shooter's workshop and found cases of .303 and 7.62x51 stored in dubious conditions. The bullets hadn't deteriorated, but the cases showed a lot of corrosion. Thankfully there is a base nearby, and I made a midnight drop at the amnesty box. It had been military property once upon a time, so they got it back.

Afghan vets will recall the shyte condition of captured and recovered ammunition. The Taliban would leave caches in other people's compound walls, then get killed before retrieving their stash. Our guys might find it doing a search. Supposedly it was still very serviceable under the dust and bad visuals.

I didn’t like the attitude of his first post here. Now the guy who chose to name himself “ I don’t care about you” on the internet says that the internet makes him worry about humanity… maybe he should talk to an expert.
 
As someone else said tumble it or use some steel wool to clean it up . you said x39 ? shoot one round at a time . remember feed it into the chamber from the mag. and make sure that the bolt closes all the way home .
 
Back in what feels like another life at this point, I can visualize the guns/ammo that were hidden by immersing them in honey pits (outdoor toilets), buried in swamp mud and even in used cooking oil.

With a bit of TLC, they were never pretty but they all went bang, without any issues, other than the very odd failure to feed.

Milspec ammo is meant to be stored under outrageous conditions and with very little fuss, be washed off, stuffed into magazines and loaded/fired from the platforms they were designed for.

One of the few times I can remember this being an issue, was before my own time in the field, and it involved the first American ARs that went into service.

Why it wasn't picked up in the extensive testing before being accepted ???????????

There are many here much more familiar and knowledgeable about these ammunition issues than I am, but basically the rifles suffered from all sorts of issues, such as failures to feed and go into battery from dirty ammo, wrong propellants etc. They had enough trouble that they incorporated a ''forward assist'' mechanism to help push bullets into the chamber with pressure applied by the butt of the soldier's hand, which usually got things working as intended.

Nothing worse than being in the middle of a stressful situation and getting a failure to feed, seat or go bang. Right when you least need that to happen.

Those old Soviet designed firearms and their ammo were and still are exceptionally reliable. They're not as tight or slick as the AR and other platforms but any one can operate them after a few minutes of training and the components are very strong, sloppy and acceptably accurate for the purpose they were designed for.

The early problems with the M16 ammo had nothing to do with the case. It was a result of the military industrial complex and probably some self important general deciding that the propellant powder specified by the rifle manufacturer didn't fit within the desires / wants of said group or individuals and thus could be ignored. The wrong propellant resulted in excessive fouling and unburnt powder in the chamber and upper receiver, which caused the well documented failures to cycle. It also didn't help that at first the troops were trained that the rifle didn't need to be cleaned as often and the rifles were initially issued without individual cleaning kits.
 
IIRC, excessive use of calcium carbonate to neutralize the remaining acids lead to the nasty fouling that the gun couldn't handle. You couldn't really clean your gun often enough. There is a US Army document out there with pretty much absolute insight into the problem.
