The few steel cased rounds I have spent worked just fine in 9mm and 5.56x45. Still brass or nickel plated brass has not harmed the magazines, extractors or ejectors because the brass is soft. I haven't broken anything with the steel cased ammo.
I've used both the lacquer and polymer .5.56 ammo with no issues. I've used Wolf in 45 ACP, and 9 MM. I'm currently running through about 2k of WPA 9 MM with no issues in anything I've shot it through. The only issue I had was out of a brand new G23 running a 9 MM convesion barrel. The new recoil spring needed about 200 rounds of full power FMJ before the gun would run on anything steel cased.

The mild ("soft") steel used in steel cases has a similar hardness to brass. It is significantly softer than the harder steel used in extractors/ejectors/slides/bolts/etc.
You won't break parts in your gun by using steel cased ammo. That's more internet urban legend BS. Not all steel is created equal; there's a wide variety of steel formulations with different properties for different purposes.
Interestingly, Mike Pannone has been putting out a lot of material where he is shooting steel case Rooskie ammo through his 2011 without any issues at all. I think he’s above 8k so far with zero issues.

If you haven't checked it lately, you should.
Back ~10 years ago, when Wolf first switched to polymer coated ammo in response to the BS interweb hysteria about lacquer, I had bought a half case of their new polymer-coated 7.62x39 that I transferred into an ammo can, which I stored in a climate controlled house in the bedroom. After a couple years, I cracked open the ammo can to find tiny rust spots all over the steel cases.
At that point, I went back to stocking lacquer coated steel 7.62x39 only. I have lacquered 7.62x39 that's been stored in the same manner for nearly two decades with no issues, and have many cases of lacquered surplus 8mm and 7.62x54R ammo that's ~70 years old that's still just fine. Luckily, there are still a few companies that haven't bowed to uninformed keyboard commando false outrage and still offer lacquer coatings. (Golden Tiger is my go-to for lacquered 7.62x39, but Wolf itself even still sells lacquer coated steel ammo in various calibers, although it's not as available as it once was since most of their contract production ammo is now polymer.)
Also, Wolf may have perfected their polymer coating over the past decade+. I haven't had that issue with some more recent poly-coated Wolf .223, but it also wasn't stored for very long before being shot up.
I bought Wolf .30 carbine and in the 500 rounds I’ve shot so far I have not had a single issue. I’ve also put about 100 rounds of Tula thru it without any issues. The WWII warhorses feed any ammo you put thru them.
