1988 vintage Russian (USSR) .22 RF ammo, corrosive?

[His lordship.]

I bought 3 boxes of different USSR .22 rf ammo at a local gunshow and am wondering if it is corrosive?  The .22 Shorts say "non-corrosive" and the steel cased ammo is dated 11-13-1988, or at least that what is seems to say.

I remember a situation in the early 1990's when there were Russian made 9 X 18 Makarov ammo that came into the country that stated it was "non-corrosive" and turned out it was corrosive.  The poor ammo sellers had to take a magic marker and blot out the "Non" on the box.  I was lucky as I had religiously cleaned my Makarov with Hoppes #9 after shooting it and did not have a damaged barrel as I had used several boxes of the Russian stuff myself.

This recently purchased ammo is not the Wolf brand, or the same packaged steel cased stuff that was available in the mid-1990s.

I usually don't clean my .22 rf gun's barrel on a regular basis, but if this stuff is corrosive, my guns will have to get the bore scrubbed after each session.  Has anyone used this stuff from Russia?

Thanks.

Got a friend that bought a bunch of it. It stinks and is greasy and a steel case but the stuff we shot was not corrosive.

I finally got to shoot it with my CZ-452 rifle.  The steel cased stuff had a lot of misfires, had to reload it into the clip to get it to fire off, some shells needed 4 primer hits.  I also had some misfires with the .22 shorts, not as bad with the other brass cased Russian ammo. 

Will try to see how the Russian ammo works in my .22 semi-auto handguns and revolver.  All of the ammo was sooty, greasy and generally not reliable.  I went ahead and gave my rifle a really good cleaning just in case there was a corrosion issue.

I Don't plan to buy anymore of it at this time.  At least the steel cased stuff did not jamb in the chamber like the Russian ammo used to do back in the 1990's.
