The only steel case ammo I have is Chinese bulk 762x39 SKS/VZ/AK ammunition. It works fine, I've shot samples out of dozens of 1440 round containers we've received (bought/sold millions of rounds of this), and never had any serious complaints about the steel casing.
I've not run any of the steel case pistol or 556/308/etc ammunition however. Lots of YT vids out there of guys using it with no ill effects, probably depends on the brand, type, and what Maverick said, what type of barrel and chamber you're pushing it through.
