Norinco "non-corrosive" 7.62x39 warning

There is simply no way this is due to storage or previously used corrosive ammo. As stated, it is the ONLY one in the exact storage conditions with ANY rust, nevermind this much and was cleaned BEYOND thoroughly prior to this with a full strip down. In addition, the rust is ONLY in areas with powder accumulation. Great if no one else had a problem, but my batch is suspect.

First I've seen of any new production Norc being corrosive, were corrosive primers even still a thing in 1991? Is there high humidity there? This is a bolt from one of my sks's that I've purposely let sit since October, this is 60-80 rounds of corrosive Czech, and it's no where near as bad as yours

 
Of all the thousands possibly into the millions of rounds of this stuff sold this is only the second time I have seen any issues. Perhaps you got a bad batch, most likely the problem is outside the ammo. That really is some terrible rusting though.
 
I wouldn't put it past Chinese ammo makers to find some old primers and put them into new ammo, but this is odd. Another 200 rounds yesterday, no rust today....
 
My SKS is fine, thank god. And that pic is the exact same as the ammo ive got.

Im going to have to keep a eye on my sks's after shooting it i would hate for there to be a box of 20 corrosive hiding somewhere in my crate that rusts up my guns.

That was the case with the 2011 head stamped Norc 7.62x54r Canam sold, they acknowledged it and made good on refunds and then sold it discounted as corrosive x54r. OP should do a nail test from rounds out a few different boxes of his ammo, if it fails I'd contact Canam and see what they can do. They are a stand up dealer.

Thanks for the info. I will do it and report back. With my luck, it was one box of the batch and won't be able to reproduce the results.
 
I just saw I need to set off the primer for this test...not sure how that will go over in suburbia. Maybe I'll bring it to the range with me over the weekend and do it there.
 
The primer is not very loud.

a hammer and nail is louder.

If youmhave a garage or shed, hardly anyone would hear it

edit. Just make sure you take the powder out!
 
I had to go and check all the rifles that may have fired norinco ammo and they are all good, but I always clean ASAP.

I have found the PPU primers provided a real light show when compared to some ammo.

I disagree, was testing the indexing on a revolver, no powder and putting the revolver out the back door (I live in an area I can discharge and safely) and that pop was something to make your ears ring for a while, a lot louder than a 22LR going off, this was a Large Pistol primer.

I guess my thought of if you don't have time to clean it don't shoot it comes to mind. My boys first sks did that after 20 rnds he learned that lesson. Goes for all my guns

You sure don't need to do a full strip and clean after every outing. unless you are shooting corrosive; The OP purchased "non-corrosive" ammo.
 
Quick update on this... I checked some of the cases a while after shooting and there is no rust inside like there would be with corrosive steel cases. I am baffled at this point. As stated, I did not shoot corrosive and it was cleaned beyond thorough prior to this outing. Maybe there was a few corrosive primers somehow mixed in, maybe I just have terrible luck. In any case, it looks like the vast majority of this ammo has no issue as expected.

The good news is, I was able to clean it up quite well and it shoots just the same as it did.
