Mystery 5.56x45 Ammunition. Corrosive or NonCorrosive?

[JIMDICE]

In the back of my safe I found an old metal tin marked 5.56x45, 800 rounds. It looks the same as the metal sardine tins CanadaAmmo is bringing into Canada right now from Norinco. The tin is also marked: CJ-5-3.

I would like to know if anyone else picked up this type of ammunition. I must have picked it up at a gun show back in 2001. I'm not sure if it's corrosive or non-corrosive. Any opinions?

Thanks.

chinese, non-corrosive

Is there such a thing as corrosive 5.56mm?

Don't think so. There might be old corrosive .223, but I believe the 5.56 has always been non-corrosive.

Holy, I wish I could find 800 5.56 rounds in the back of my safe

There may be, but I have yet to see any corrosive 223. It would likely be 60/70s Combloc for captured M16s, if it exists.

Are they making 5.56 in Peshawar? - If so it'll be corrosive (and probably have large primers)

Big thanks guys. Someone offered me a tin of the stuff and I always assumed it was corrosive and just forgot about it. I'll crack it open and let you know if there are any primer markings.
