I have found that you will want to run the upper "wet" when shooting Wolf. If the upper is on the dry side, the powder fouling from the ammo will gum things up after a couple hundred rounds.
That said, don't run the firing pin wet. You want a very light coat to no coat of oil on the pin. The pin is hard chromed after all, so it is not going to wear out from lack of lube. If you put the pin back in dry, but heavily lube the outside of the bolt and carrier, enough lube will eventually pentrate inside the bolt to provide a light coating on the pin anyway.
If the lube is heavy on the pin, the powder fouling will congregate on the pin, leading eventually to light primer strikes. I have have seen it happen personally. If you were to let the rifle sit for a few months without cleaning, the mixture of powder fouling and lube could harden up, which could lead to slam fires.
