I know berdan primed ammo can be made with non-corrosive BUT what about the potential errors and cheating?

When you buy steel cased berdan primed ammo, you stuck trusting the manufacturer's claims that it actually is NC.

If you look at reviews of Norinco's supposedly non-corrosive 7.62x39, modern production berdan primed ammo you'll find that many reviewers say that the stuff is obviously corrosive.

I know that the Chinese ALWAYS tell the truth, right? What do you say?
 
I treat all steel case as corrosive.. I just ordered 1000 more from cabelas will do the nail test and if it proves corrosive I will just call my credit card and cancel the payment lol.
 
I've used lots of Norinco ammo that is packed in individual cardboard boxes- white box, red box, silver box- and it's never been corrosive.

Spam cans are when things can be more complicated. I've used lots of spam can ammo that wasn't corrosive, too. And lots of spam can ammo that was corrosive.

Personally I think the whole corrosive non corrosive thing is overblown. Some folks seem to think if you take a few shots in your T81 using corrosive ammo you have to rush home and submerge it in Windex immediately :)

I've got a 1949 SKS without the chrome lined bore, so I care. Ditto for my 7.62x54R SKTs and Mohawks. Yes, I know how to clean it properly - "so it shouldn't matter" - except that with the SKT and Mohawk, detailed cleaning takes the scoped gun off zero. You can't sight-in the gun with corrosive and put it away.
 
Do your own tests, if you are soo worried about your guns.

You focused all your time on finding what you consider inferior brass. I think you can find time to do your own testing if something is corrosive.
 
Simple to use a funnel to run boiling water thru chamber, bore and gas tube; then clean as usual. It only adds 5-min to the job, you should clean anyway.
Just my an-l opinion.

interesting point. I would be interested in how anyone with a sniper SVT handle post corrosive ammo use.. I only use non corrosive ammo in mine because of this issue.
 
The only recent Norinco retail boxed ammo I have found to have corrosive rounds mixed in bear the headstamp 311 18 on white box.

Everything else I have shot, including 311 14 white box, 311 19 red box and 311 20 red box have been non-corrosive. I deliberately don't clean my piston tube, rod, barrel, action, breech, etc. for days, sometimes weeks after shooting hundreds of rounds, and found no issues.

The retail boxed stuff differs from the spam can stuff, which is corrosive.

Best to keep things segregated and test using certain headstamps at each range session, rather than mix and match.

Cabela's sold the white box stuff previously that had corrosive rounds in it. When they switched to red box, unfortunately they kept the white box photo on their product page, which caused a lot of consternation. The recent batch of red box is all good as long as you are getting 311 19 or 311 20 (which I believe is what Cabela's is selling now).

Chinese? Hit and miss. Certain headstamps are, certain headstamps aren't. Anything that is Russian factory ammo like Barnaul I trust to be non-corrosive.

Barnaul was the best but unfortunately we can't get it anymore :(

It's weird. No retailers are stocking any Barnaul 7.62x39, yet a number of our site sponsors and other retail brick and mortar stores have Barnaul .223 on their shelves. Maybe the comparable brass version is close to the same price, whereas the 7.62x39 brass versions are considerably more than the steel case.
 
Barnaul 7.62x54R is still available near in Eastern Ontario. I'm not getting great accuracy with it. My reloads with x39 projectiles and a 1.5 times dump of AK powder do much better. Ditto for 1975 vintage Chinese x54R corrosive surplus.

BTW ever heard of "mildly corrosive"? That is an oxymoron like "jumbo shrimp", or "deficit budgeting", or "Ford quality", or "military intelligence" or "feminine hygiene", or "Trump administration".

Now that was good thank you . Jumbo shrimp lol . it's the dam primer . if your worried just clean it . I just received a text from a buddy in Texas . he told me that the price of ammo is dropping in his State . must be nice. he only had 3 pistols when I first talked to him in many years . 3 years later he has lots of rifles and pistols and other goodies . it only took a little coaching .
