Wolf/younameit steel cased ammo has the reputation of being dirty, smelly, and at times can cause problems with the laquer or polymer causing cases to stick in the chamber. As far as being dirty and smelly, um, ok , I've never used it, and I did see an interesting article at the box of truth about steel cased ammo. He'd shot some and followed it with some brass ammo and the brass cases stuck in the chamber. What he'd concluded with some input was that the steel cases weren't expanding fully allowing carbon to build up in the chamber. The brass cases then stuck to the chamber as they expanded fully and welded with the carbon build up. Carbon build up or whatever, lots of people shoot wolf with no issues. A lot avoid it.
But 230$ for 1000rds is hard to not go for, but then again, I don't want my sig smelling like a litter box :lol:
