The bullets in Wolf ammo are under size we are told .263 not .264 so they may not fully engage the rifling especially on R5 rifling. I have not and will not shoot it myself in my Grendel's. I have shot their 7.62x39 lacquer coated steel case ammo in my SKS's but cleaned the chamber really good with lacquer thinner every so often because when the barrel and chamber started to get hot the lacquer on the cases would melt and cause function problems. That is the reason that Wolf introduced the poly coated cases. I am not sure what coating their Grendel ammo has.
