wolf ammo review

I use Wolf almost exclusively in my SKS with no problems. I saw a 7.62 on a AR platform that would short cycle after 15-20 rounds. The owner said he thinks it's the Wolf ammo clogging everything up. Anybody shoot Wolf in their .223 AR's with any problems? Or maybe it's just that platform with...

any good? OK?

Does any one know if wolf ammo is crossive or not? If it is crossive then do you know of any ammo like wolf that isn't crossive? Because I want to by some bulk ammo.
