A question for people more expert in ammunition issues than myself.

http://www.rustywood.ca/ is advertising the following:

Chinese 7.62 X 39 Ammunition
Crate of 1440 rounds (2 X 720 Spam Cans)
Packaged in 1972 - Copper washed Steel Case,
Non- corrosive berdan primed 123gr soft steel core copper jacketed boat tail bullets.

It seems like I have read here that pretty much all surplus ammo made earlier than the '90s is likely to be corrosive. I am interested in their product, but I don't want to pay more for something that turns out to be corrosive, or where some of it turns out to be corrosive, as has happened with some other ammo that is advertised as non-corrosive. Was there military ammo from the PRC from that era that was not corrosive?

Thoughts anyone?

Thanks in advance.

Cheers
 
I have bought a few crates of this stuff. It's like shooting an old black powder gun... DIRTY !!! I haven't come across any "corrosive" indications however, I do thoroughly clean all my firearms after every use.
Also, my polished nail tests showed NC but thats a pretty primitive inconclusive test in itself.

I believe the true story behind this is the supplier sold it as NC and therefore the cdn distributers are legally allowed to sell it as such.

In my opinion, treat it as corrosive and have fun ! for under $300 you can't really go wrong.
 
Just like AROD89, I haven't seen any indication of it being corrosive (I haven't really tested it), but it is really dirty. I'm an obsessive cleaner, so I just treat it like I would corrosive and clean after shooting.
 
I emailed the vendor cited at the beginning of the thread and asked him about the ammo, and here was his frank and honest reply:

Well that is the million dollar question isn’t it.

I tend to agree with you BUT the importer/wholesaler I buy it from swears it is non-corrosive and sells it as such.

I tend to think that it is corrosive and you are best to clean your gun assuming it is. I have some Russian 1887 surplus 7.62x39 in stock and it is still listed and sold as corrosive. I suggest you are better served buying it as it is cheaper and in stock and just take the extra effort to clean your guns after each range session.



I have several SKS rifles and an AR that is in 7.62x39 and wash with hot water after each range session JUST IN CASE. If you use boiling hot water as last rinse it tends to dry fast by itself almost and I then oil it down with a good oil and wipe off with rag – DONE.



IN SHORT _ I buy it based on the wholesaler saying it is NON- CORROSIVE but I cannot guarantee it is to be honest. I have no way of testing to be sure.

If you search any of my comments in any of the lever arms threads the 1972 stuff is SOMETIMES corrosive. I got the 1440 crate, shot 400+ rounds without any issues, no rust, a little dirty, but hey, it's surplus. Then i got into a couple bundles that were corrosive, but i wasn't cleaning it right away because it's the "non corrosive" ammo i was using. Well, a week later i take out the sks i was using and had rust growing out the end of the barrel, all over the gas rod/tube and some in the chamber.
So long story short, treat it as if it is corrosive, or if you are going to do a primer test, you basically have to test each paper bundle (and even then it may be mixed within the bundle)
The only good part of the story is from looking at where the rust was i now know where i do and don't have to focus on cleaning really well when i am using corrosive
 
I cant see the problem with the ammo myself, other than it being sold as something it may not be. Its good practice to clean your gun whenever you have fired it, be it one round or four hundred, corrosive or non corrosive. I use the dirty cheap stuff all the time with no problems at all and it doesn't take 10 minutes to tear the gun apart clean it oil it and toss it in the closet.
