Hey Guys

Friend at work said that a local gun store has Non Corrosive ammo. 1440 rounds for $275. In non painted crates.

Old fud behind the counter would not let me take a picture of the crates of ammo. He says there is no more corrosive ammo in Canada!!!! lol Fudds

This looks like Corrosive to me??

Thanks

It's corrosive! Anything with the factory code & year of manufacture on the base like that AND CHEAP, I treat as corrosive...

Cheers

There is a chart of headstamps floating around that lists all the headstamps for 7.62x39 and then tells if it is corrosive. I wish I could find it as I have some old Chinese surplus that looks like that. I think it is corrosive. My guess it was made in 1971 so a person would have to see when they stopped using corrosive primers.
 
I've had that exact same headstamped ammo, it's Chinese. Mildly corrosive, but still corrosive.

Break out the kettle and boil up some water unless you like rust.
 
why not test it? Pull the bullet, dump the powder, and discharge the primer so that the exhaust lands on some steel. Let sit for a few days and see if it rusts?
 
Chinese production, 1971 manufacture. Definitely corrosive. Chinese stopped using corrosive primers around 1985.
 
I dont buy anything but the corosive stuff :D
Fire a clean hunting round thru at the end of a session , sometimes wash it down with brakecleen then oil ...sometimes just put away
Theres a small amount of rust on it yep...its a cheep gun that honestly im not all that worryed about how it looks...but she shoots nice at a hundred yards;)

I think thats china brand ammo as well
 
Just curious, how all the guys in the US with their AK's shooting 7.62X39 deal with this corrosive/non-corrosive issue, .... or does the US have NON-corrosive for them (but not for export) ? Anyone know ?

IIRC, steel core pistol ammunition is unimportable into the US due to their laws. Why am I talking about pistol ammo, you wonder? Because 7.62x39 M43 surplus is considered a pistol round in the US due to a company down there (Olympic arms, I believe) making a 7.62x39 AR-15 "pistol" in the 1990's despite an extreme amount of protests from gun owners telling them not to. After they did that, the BATF (a**holes to the highest degree) classified ALL 7.62x39 M43 as steel core pistol ammo and banned it from import. In the US, they get cheapo ammo in this caliber as well, but it's not corrosive and while the casing and powder is surplus, the actual bullet itself is not. All the 7.62x39 ammo from the company known as Wolf is an example of this. I am sure there are others, too, I just don't remember them off hand.

Because of this, making a 5.45x39 "pistol" is a very taboo subject in the US as they can still get cheap and decently performing corrosive surplus in that caliber, designated 7N6 in Russian usage. If someone were to make a "pistol" in this caliber it would become unimportable as well, leaving AK-74 owners in quite a tough spot for a while until Wolf or something started sending them cheap-ish 5.45 that the ATF overlords deemed acceptable for the peons.

No nation is immune to government idiots who love making stupid gun laws.

This basically makes corrosive 7.62x39 M43 surplus somewhat of a rarity to our southern neighbors as the stuff imported before the ban has been mostly all shot by now, although still sealed spam cans of it occasionally turn up on sites such as gunbroker for a somewhat inflated price. I think an exception to the import ban on 7.62x39 M43 is the Yugoslavian M67 ammo, which is corrosive, as it's a bit different, but I'm not 100% sure on that. If it's considered importable into the US, than I would imagine they guys with AK's down there clean their rifles much like we do, with water or Windex. Corrosive ammo isn't some unheard of thing in the US, as corrosive surplus 7.62x54r, 5.45x39, 8MM Mauser from Yugoslavia, and as I said possibly Yugo M67 7.62x39 and other calibers are all importable and very popular in the US, so the awareness for cleaning after shooting corrosive ammo in the US is quite similar to here in Canada.

A thing to keep in mind is that all this corrosive ammo was issued in Communist countries for years, and you don't hear too many stores about AK's and SKS's rusting shut from former troops now that the cold war is over. While cleaning appropriately after shooting corrosive is very wise, it's not the end of the world if some surface rust appears on your rifle. Just attend to it before it turns into pitting.

There's no reason we couldn't import this Wolf ammo for ourselves, but there isn't much point considering it'd probably cost a bit more to do than surplus, and we already have decently priced non-corrosive steel cased stuff here from MFS. Another thing to keep in mind is that in some of the dryer states, such as Arizona, there isn't really any moisture in the air for the corrosive salts to actually harm your rifle. A video gaming friend of mine from Arizona has an AK-74 that he shoots nothing but corrosive ammo out and has never cleaned once that doesn't have a speck of rust on it due to the dry air.

But yeah, as I, and everyone else said, the ammo in OP's pic is indeed corrosive. Whoever said it wasn't was, intentionally or not, being misleading. I had 1440 rounds of the stuff with the same headstamp and it was mildly corrosive. Some of the least corrosive surplus I've ever shot, but still corrosive. Good news is it shot very well for surplus and is quite inexpensive: I love surplus ammo for reasons such as this. As for the fudd saying there's no more corrosive ammo in Canada, I'd love to refer him to every case of surplus ammo in this caliber I have ever bought and tell him to run it through whatever x39 rifle he owns, if any, and not clean it as if it were surplus. I think he'd end up regretting that after a week or so. Especially for a spam can of Polish ammo I had a while ago, YIKES! I think I've seen salt that was less salty than that ammo. :p

Now with the windex issue. I used to rock the windex and then bore snake it. This worked awesome but not perfect. I figured there was TOO MUCH water in it and then went and 'bought' some ammoniated floor cleaner that was meant to be mixed with water to clean floors [i stole it from work]. I use that, without water mixing, from a spray bottle and it is infailable. So I'm now buying into the ammonia theory.

Why do you reckon it only works because of the water?

I've always been under the impression that ammonia doesn't neutralize salts as much as it just washes them away like water does. But I'm not sure, to be honest, maybe I misspoke when I said it "only" works because it has water in it. I'll remove my comment about Windex "only working because it has water in it" from my above post as I am the first to admit I was speaking without a source to back up my claims. I apologize for that.

I can only speak from experience, and my experience is that boiling water works just fine on all seven rifles I shoot corrosive ammo out of and is easier to wipe away than Windex as boiling water will mostly evaporate quite quickly. I've used Windex before with similar results to boiling water, although I could never get it to work on my gas tubes from all my SKS's as well as I could get boiling water to. Squirt a ton of Windex into the gas tube and then clean it normally = rusty within a few days. Pour boiling water down the tube and clean normally = no rust issues after well over a month of storage, but again, these are just my experiences.

Another thing is I have to pay for Windex. Boiling water, not so much. But hey, if you're "liberating at no cost to yourself" a solution from work and it works well for you, more power to you. So long as your rifle stays rust free, it's all good, right? :)
 
It never ceases to amaze me how the corrosive boogeyman puts the fear of god into your average gun owner. Billions of rounds of this stuff got manufactured and fired by millions of troops in conflicts spanning the decades since its introduction. You think they poured boiling water and windex down their barrels or hesitated pulling the trigger because the gun might rust?

Just shoot the damn stuff.

Don't forget that they are average gun owners;)
