I recall when Wolf first hit the market; many were worried that the steel cases would ruin extractors, bolts, chambers, and anything else that you can imagine. (Possibly forgetting in the process that steel cases are not unusual and have been used in American military small arms in the past, and didn't cause all those problems.) The cases are the last thing that I'm worried about.
I won't speculate on the Olympic issue. I've seen a preban Oly that runs it fine and I saw a later Oly that wouldn't run it at all. My Fulton Armory shoots it reliably and is not chrome lined. I use a chamber brush whenever I clean and I clean it every time that I shoot it; perhaps it's just a matter of being more careful with maintenance? I'm not sure. It's dirty, but I don't recall ever shooting anything in my AR (or an M-16, for that matter) that I'd call "clean." It's an AR. They foul a lot. That's just the way it is.
I did notice very minor frosting the last time that I did a major decoppering of the bore after several years of cleaning with CLP. I suspect that a very early batch of Wolf (as that was almost all that I'd shot through it) but I can't be sure. I've heard that the first few lots were mildly corrosive, even though not really advertised as such. As such I'm reluctant to buy more of it, although I still shoot it if that's all that's available or (as in this case) I have a lot of it laying around. It's no longer my first choice until I find out more about just what happened.
The smell is a valid complaint.
