the only surplus corrosive stuff is 7.62x54r.

all the wolf and tula 556 use wolf primers which are non corrosive. wolf makes primers for all the russkie stuff. i use their primers the most since they are cheap and often available.

black powder is corrosive as its made with salts. modern powders dont use salts so smokeless powder is non corrosive. what is corrosive, or was, was the fulminate of mercury based primers which are no longer used. the ussr switched to non corrosive primers a while back. what we are getting in the form of surplus is all their old stock of 7.62x54r that come in the big spam cans.

one way of removing priming salts is hot soapy water.

thank you for the clarification. i wasn't as sure about the primers.

what about surplus 30-06 ammo being corrosive? some of that ammo can go back quite a few years.

i was referring to steel cased soviet ammo since that was the question.

yes quite a bit of old surplus 30-06 in brass case is out there. practically all of it.

The commercially loaded stuff uses non-corrosive primers. Even a lot of the newer mil stuff is fully non-corrosive now. Some of the steel case uses Boxer primers, and some still uses Berdan primers, but most folks have gone the non-corrosive route even with the Berdans, at least in the commercial stuff.

There are still a lot of crappy AR's out there that are picky eaters when it comes to ammo. I still hear someone crying that their AR won't cycle steel case ammo, and I just keep shooting it. I suspect often it is because they have .223 barrels even though the markings say 5.56. Then they say it is because I have a piston, and they don't, but they look for another excuse when I pull out my DI gun and still shoot it.

IMO, i don't think the AR's are any different than other firearms. some are just picky about ammo. i shoot a lot of Federal and PMC ammo in my AR and have never had a problem. i have never shot any steel cased ammo in mine, simply because it's just readily available where i live. i'd like to try some out to see just how it does perform with it though.

Some of the cheaper AR's will come with a disclaimer that says they will void the warranty if you shoot steel case, import, reloads, or hand load ammo.
