As far as I know Wolf really IS noncorrosive. But also as far as I know, Russian military doctrine still uses corrosive (or what some call "semi-corrosive") primers because apparently these primers are far more reliable under sub-zero conditions. It's easy for us to forget that most of Russia is a frozen iceburg much of the year.
HOWEVER, having said that, I'm also a cheapskate and shoot corrosive milsurp ammo most of the time. The way to keep it from ever harming your rifles is to clean the bore, chamber, and bolt throughly with ammonia-based Windex while the barrel is still hot from shooting. When the patches come out clean, run a couple of dry patches through, and finish up with one soaked in oil. Yeah, it means an extra ten minutes at the range, but it also means the regular cleaning at home takes no time at all.
