Hungarian 7.62 x39 mm ammo

[STEVR]

Went to a local Vancouver gun store and was looking for some ammo to feed my new CZ-858 Tactical "Bad-Boy". He had very lethal looking hunting ammo made in the USA which was not corrosive BUT was expensive- about a buck a shot. He then said he had some 7.62 x 39 Hungarian ammo. The store owner said that his distributor claimed that the ammo was non-corrosive but the store owner was not 100% sure. Although he no complaints re corrosion from the Hungarian ammo, the store owner is a tad skeptical of ammo from the Eastern Block.

My question: Hungarian ammo good.....ie non corrosive? Hungarian ammo bad.... ie Is corrosive. The ammo is FMJ 123gr made in Hungary- company name is "MFS".

Gentlemen let me know what your experience is with this particular ammo or if you know for sure if this ammo is 100% corrosive or not.

Non-corrosive (left it a week still no rust) and shoots well.

7.62X39 doesn't supposed to be corrosive.... like 308, but, you never know...

 

[baldman]

definitely corrosive, from personel experience. Still good ammo. Just clean properly after using

Berdan primed = corrosive
Clean your gun...

Is this the Stuff?






The Casings are more of a dark silver grey instead of a dark brown.

the Guy who sold it to me said it was "Mildly Corrosive" or "Half Corrosive" Whatever that means. I haven't fired any yet I have some Norinco ammo left but want to save it.

It's very corrosive(make that VERY VERY VERY, like the worst ive ever seen, corrosive). Left it a week and still no rust? What did you shoot it in, a Norc SKS? The Barrels on these are chromed(wont rust) but the gas system is plain steel and will rust solid...Hope your gun still works!

Not all berdan primer are corrosive, in fact most aren't. But most com-bloc ammo is.

I have been testing this ammo and here are the results so far.

Ammo tested

The steel plate used was cleaned with a wire wheel then de-greased twice before primers were fired. A to E are 7.62x39.

After 30 days.

The MFS 7.62x39 boxes contained rounds with 2 different headstamps 21 81 and 21 85. The 21 85 also has sealed primers, there is no visible sealant on the 21 81.
Powder weight averages 24.36g with a standard deviation of 0.206 which means the powder weight is very consistent.
OACL averages 2.186" with a SD of .002, again this means OACL is very consistent. These numbers represent a sample size of 20 rounds.

The 7.62x54R boxes contained rounds with all the same headstamps 21 52. No evidence of primer sealant visible.
Powder weight averages 50.92g with a standard deviation of 0.363.
OACL averages 3.016" with a SD of .005.
Based on the numbers for powder weight and OACL it appears that the ammo is made on different machines but they appear to be fairly consistent. These numbers also represent a sample size of 20 rounds.

Both rounds used extruded powder. I will eventually run these rounds over the chronograph.

So far it appears that this ammo is NON-corrosive, it is pretty dirty and the 7.62x39 should be the more accurate of the two.

Tango2, it looks just like your photos...but no stipper clips. The box looks the same as well.

Half corrosive???? ....ok? So the Czec stuff is more corrosive?? Hmmmmmm?

A good reason to not believe everything you read. I had been led to believe all berdan was corrosive. I stand corrected, I guess...

Yeah the Stripper Clip is my own. I have it ready to go for Cyote defence, I was just too lazy to open the box and take a few out for the photo op. I only own one stripper clip anyhoo, will have more I guess when I order a crate of Ammo sometime in the future.
