If you're getting a deal on the stuff, there's no reason not to use it. The Rusky steel-cased stuff is generally considered to burn a little dirtier, but that ain't a serious concern.
The primers are also found by some to be a little hard, but that also isn't a major concern.
Some people avoid steel cased ammo because they think it's going to be harder on the ejector and extractor than brass cases (which obviously doesn't apply to revolvers), but from everything I've read, going back years, the low-grade steel used in these casings is actually softer than the brass casings in higher quality western ammo.
So, again, there's no good reason to avoid it, as long as it's economically competetive.
That being said, Italian-made, brass-cased Perfecta has been running $15 a box at Wal-mart for a good while now, and me and lots of others have found it to be very consistent and clean.
