7.62x54R headstamp question
Hello ,I found a box of 7.62x54R cartridges while cleaning my gun room today and was curious about them.The headstamp reads"N N Y 1989" I'm guessing this ammo was made sometime in 1989 but I was more curious about the N N Y part and if the stuff is corrosive as I hate to fire corrisive primer ammo in my guns.Can anyone help me ,I'd like to know. thanks in advance.

So,is it corrosive ? 0 -
Most likely yes it is corrosive primed. 0 -
Well that's just dandy,I remember paying 6 bucks at the pawn/gun shop in New Mexico for it and now I find out its what I don't like shooting.Oh well,thanks for the info.Will just regular gun cleaning solvents work cleaning the residue or will I have to do anything additional to clean it ?.I have some Hoppes Elite solvent and I think maybe that'll do the trick.
just did a bit of research and I found out the ammo came from the Sportsmans Guide and they say it's non-corrosive and from what the feedback on the site says,its true.the box its in reads:"7.62mm Metak
CA Tewkhm 3phom M30" anybody else have this stuff or know what the writing means ? I'm not firing it until I get some word of whether its non-corrosive or corrosive.0 -
My understanding is that *ALL* military surplus 7.62x54R from the former Communist countries is corrosive: Bulgarian, Yugoslavian, Polish, Russian, Czech, etc.
Unless its a commercial load (eg a modern hunting load) specifically labeled as non-corrosive, I'd assume its corrosive.
But the risks of "corrosive" are overrated, IMO. So long as you clean your gun after shooting it, you won't have a problem.
I don't know about the "elite" product, but Hoppes #9 will clean up the corrosive residue, as will many ordinary gun solvents.
If you can't/won't clean your gun immediately after shooting, you can spray down the bore with Windex or another ammonia-based cleaner and run a patch through to neutralize the corrosive acids edit: salts until you can clean it.0 -
I'm not sure if it is military surplus ammo.I can't read Yugoslavian or Russian so I don't know if it is a commercial load or a military load.All I know is its brass cased,Berdan primed,182 grain FMJ and the product picture on the Sportsmans Guide website says its non-corrosive as does some of the customer feedback on the product page.If its non-corrosive,great no worries of corrosion from the ammo,if its corrosive,still not a big deal,but I just have to be a little more vigilant with my cleanig routine. 0 -

Ya, cleaning up after shooting corrosive primed ammo takes all kinds of voodoo and special cleaners [}:)] IE a couple 3 patches that are sloppy wet with WATER, followed by regular solvents and oil.
The corrosive component is a SALT, which while not corrosive in it's own right, it will attract moisture from the air which in turn causes the rusting. Flushing the barrel with water, washes out the salt residu.0 -
Ditto to what Tailgunner said. There's this myth floating around that corrosive ammo creates some sort of acid and that ammonia neutralizes it. Bunk. It leaves pottasium chlorate (or chloride I forget) which is a salt. Salt is very stable and can't be neutralized. But it attracts water (hygroscopic) just like a salt shaker on a damp day. This then causes rust, and eventually pits if it is humid out.
Hot soapy water dissolves these salts and rinses them away. Use a few wet patches, or do what I do- just stick a funnel in the breech (transmission funnels that are long and thin do great) and pour a pint of boiling water through. End of the problem. A few dry patches then clean as normal, lightly oil and put away.
NNY comes from the PRVI partisan factory in Serbia, or once Yugoslavia when there was a Yugoslavia. It's good ammo and MIGHT be non-corrosive with that late manufacture date, but I sure wouldn't risk it when the clean up routine takes an extra 3, 4 minutes to be sure.0 -
Jonk: so the ammo I have is from Prvi Partisan. What was the cut-off date for corrosive primed ammo from that factory ? It came in a plain cardboard box with a white label with,I guess,Russian writing on the label.thanks for the info,and I guess I'll fire the stuff and just clean my gun a little heavier than usual.Thanks everyone.And Tailgunner1954:Thanks for the sarcasm,I got a little chuckle out of it after I read my idiotic question. 0 -
Well I don't know of a cut off date, but know they switched to commercial manufacture in the 90s and THAT is non corrosive. Any military stuff I'd treat as corrosive. 0 -
being polish has its rewards.[:D]
Metak = bullet
Tewkhm = basic
3phom = ball type
its slovakian.0
