I wouldn't run wolf, specifically because in 2010 they changed how they made their cartridges which is resulting in stuck cases. However, steel cased in general I think gets a worse rap than it deserves - if you know what you're doing and run the gun correctly it shoudl work fine.

The guy uses brown bear now exclusively - another steel-cased round - and has experienced no problems.
Mostly I think the bad rep steel cased ammo gets is because guys buy a case and take it out withoout understanding that its a different type of ammo that needs to be run a little differently than your high-pressure M193 loads.
