Another issue with alot of the steel cased ammo is the rust proofing laquer the cases are coated with. When it gets hot enough, a round sitting a few seconds in a hot chamber is enough, it will melt, coating the chamber, making it harder, with each round chambered/fired, for the actions to open, and cases to be extracted, causing yet more stress on not only the extractor, but the action itself, it also makes it harder to get the chamber clean, lots of brushing, and bore cleaner is needed, and will jam up an AR quick. Wolf makes the polycoated cases, but some of the earlier coating tended to scratch off into a fine powder, had this happen with an AR, causing the rifle to jam.
Some combloc countries copper or brass wash their cases, basically a thin electrocoat of copper, or brass, this is eliminates the mess, but steel cases are still steel cases, and some companies will void warranties if steel cased ammo is used.
Another thing to look at, some of this stuff is repacked milsurp, Wolf military Classic is such, and may have corrosive primers.
I do shoot steel cased ammo, but only in AK and SKS rifles.
