Corrosive ammo?

[Rembo]

Can anyone tell me if this is corrosive?

Thanks

Pic didn’t work bro
But probably lol

Link is there, this site won't pick it up. Nothing new here lately. Sometimes it shows up after a few hours.

Looks like a 700 round can of M43. So most likely corrosive I would imagine.

I've been wrong before though. It might be x54r. What was it sold to you as?

 

[Rembo]

I was told it's 7.62 x 39. Maybe it is 7.62 x 54. I may have to open it...probably worth more sealed if it isn't x39...or is it?

I'd say it's a can of corrosive x39. 7.62.54 typically comes in 440 round cans.

If it comes in a spam can it’s more than likely corrosive.

I would treat that as corrosive. Clean accordingly, especially the gas system.

Being 1973 manufacture, I would guarantee it's corrosive

Thanks you're all good,

Its x39...
The 43, referred to the m43 designation of the typical 7.62x39 surplus...

You don't know what it is? Did you follow a UPS driver and picked it up from somebody's front door?

Coincidentally, it was cold and snowy today, so I dove down the rabbit hole of researching spam can markings. Out came the label maker to label the info on my cans and empty lids I had on hand.
Based on what I learned, your can has the following info
7.62 Calibre 7.62x39
nc Standard steel core projectile
rЖ Copper washed steel case (rc is for lacquered steel case)

r89 Just a lot code
73 Year of Manufacture (this is the prime info to tell you it's 99% likely corrosive)
539 Factory designation (539 = Tula)

BY0n Powder type
38/73 Powder lot number and year of manufacture

WT Quantity 700


Here is all the info I labeled onto my cans this afternoon

I think a combination of storage medium and date would lead one to a relatively educated conclusion.

I believe boxer primers didn't come until late 70s/early 80s. The spam can doesn't necessarily denote corrosive, though in conjunction with the date (1973), I would bet dollars to donuts that it is.

Some later calibers and rounds come in spam cans - ie. the 2020 Norinco .308 rounds are in a spam can and they are not corrosive.

Anything from the early 70s and earlier for 7.62x39 in spam cans I would treat as corrosive as they almost certainly are.

That stuff will eat a battleship, it causes a beautiful orange hue. Keep the dear clean and you’ll have no problems.

Simple rule if it comes packaged like surplus it’s corrosive
