hey guys, is the hungarian 7.62 stuff corrosive?

comes in a white square box, has a logo that reads MFS on it, headstamp on the ammo is "21" over top of "85"
 
I've bought it before at gunshows, I think Districorp was the main distributor. I think it's corrosive, but I haven't tried the "steel plate test".

It comes in commercial boxes but I suspect it's a re-pack of old 80s Hungarian milsurp - and I don't think much (any?) Eastern Bloc military ammunition from that era is non-corrosive. I can't say for sure, but I'd err on the side of caution. Good luck!
 
Brass primers (yellow) or steel (black)? I've seen both.
Yellow MIGHT be non-corrosive, but... the business owner who sold me some, told afterwards that he doesn't call it non-corrosive anymore. ;)

Consider it corrosive (I always do when it comes to comblock steel-cased ammo) and your guns will be happy.

PS Steel plate test, anyone? :cool:

It's Berdan primed (two flash holes visible inside), Very Corrosive.
Just wash your SKS well with hot hot soapy water and rinse well to the point that you can't smell any residue.
 
Concerning the "steel plate" test, this is something I haven't done before but I remember the topic from some time ago. I think it was about the Czech 7.62x39 when it first came on the scene, but it could have been something else on another board.

Anyway the idea, from what I remember, was this. Take a round of ammunition you suspect is corrosive, pull the bullet and dump the powder. Next you need a clean, polished, unrusted plain steel plate. The idea I think was to place the primed case neckdown on the steel and fire off the primer, with a nail I suppose. The steel plate then, in theory, would have some off the corrosive priming agent sprayed onto it. Then place the plate in a damp atmosphere and wait for the rust, from what I recall a plate tainted with corrosive primer residue would exhibit rust within days. I think there was a side by side comparison between a plate hit with a non-corrosive primer and the rusty one, the N/C plate was fine. This was that particular fellow's corrosivity test.

I'm not advocating anyone try this, I don't know if it's either scientific or safe. It could be bunk, but that's what I remember.
