Re: steel cases in my AR, okay????
If it's a high end match chamber bull barrel AR etc. then no I wouldn't, but if that were the case you probably would not be asking about shooting wolf in it.
I would stay away from the lacquer coated stuff, but I haven't seen a box of that around for a couple years.
For all other AR's oh yeah, bottom line is AR's are like glocks....expendable. Every part on them is cheap and easily replaceable. A lower is what....$150 now again, extractors $10, shell case extractor $15, last gun show had blem lowers for $79. I've put thousands of rounds of wolf through a S&W MP15T and never had a case failure and it runs fine on them. Dirty....sure, but as long as it runs reliably for range playing I don't care. Considering around here winchester white box or federal AM is $10 a box and wolf is $5 a box, after a couple thousand rounds you can buy a new lower and parts kit. After 4000 rounds of wolf at $5 a box compared to WWB for $10 a box you saved $1000 go buy a NEW AR if you want.
